In the beginning of 2002 you got close to 9 Norwegian krones (NOK) for 1 USD.
9 down to 5,71 (pr 4. January 2010) is a 36% decrease as far as I know.

But on the other hand, If it was up to me, many things would be different in my country.

I'm running a set of procomp 210 58cc CNC heads on 327/30 over motor dyno last year 6200 rpm 523 hp with edelbrock air gap rpm manifold. I have 2 set of the procomp heads, complete with valve and springs was $535.00 a set. The heads was check out by Super Car Automotive in MD found the heads to be very good shape and needed no port work what so ever - was not needed. I and seen some posted flow number can be miss leading. These head do flow
very good, Some may need some port work but minds did not. I have a set of
airflow research 210 2.08/1.65 valve heads the cost was $1850.00 I just sold them 3 weeks ago $1500.00. For me the procomp heads was the way to go for me and the money save. flow number was check for my heads was at 400 lift 223.8 at 500 lift 251.3, at 600 lift 271.7. I hop on the procomp heads when some of the cars at Budds Creek Race way and Cecil county dragway running 10s 9s - 5 was running 8s in the 1/4 mile using procomp heads. Some guys did some port and valve work. But for a hot street car or 11s to 10s 1/4 mile car I was told by a few people hop on them.

Other car I run 84 mazda rx7 with 372 mopar motor, 84 chevy S10 L98 350/40 over motor, 82 camaro 65 327/30 over small block,

I'm very happy with the heads, my 82 camaro runs 11:20 in the 1/4 mile with 373 rear gearing.

Funny, afr heads i just sold flow numbers, at intake lift 400 240, 500 271, 600 279. these heads cost $1850.00 new. The little 327 will 10s easy 410 rear with licks. afr heads not the much better than number that i got with the procomp heads I have the 58cc cnc heads from procomp. All so I have set of canfield
heads. I may never use them. I tell every 1 check the net and talk to people that run the heads. When you have cars running 10s 9s - 5 cars running 8s in the 1/4 mile that saying something. And people all over are running these heads now. Like many I did not wont to even touch these heads at 1st but after seen what people was running and the times at that track. And talk to shops and the enter net. I hop on 2 sets
at $535.00 a pair.

I will say this - I'm very happy with hp out put of 65 327/30 over motor and the hp was still claiming I told the dyno tester stop it 6200 rpm cam will pull to 7400 rpm.
I had to find sheets on the heads I had tested.

Sorry missed type 58cc procomp lift intake 400 236.4 500 268. 600 272.9

So people check the net and talk to people that run the heads. And the only way you no for sure on any heads you buy is to flow check then your self , There are so many heads out there that don't meet there flow specs....

The little mouse pull pass 09 corvette at 4800 rpm real hard the guy net even catch up with me.

And the machine shop that did the testing is supercar automotive - is Malcolm Durham shop is brother runs the shop now. type Malcolm Durham in your search there's some info about him. My family been going there back in the mid 60s

Don't LIE to support your agenda. The AFR 210 flow numbers are well known:




The 58cc procomp are actually the least flowing version, and the reason is because the chamber shape interferes with the flow curtain.

The larger chamber procomp:

Lift Int Exh
.300 161 131
.400 206 148
.500 240 152
.600 260 152

The 58cc version:

Lift Int Exh
.300 151 125
.400 195 138
.500 228 140
.600 258 141


net even catch up with you? It was even ? huh?

Automotive witch? So they use magic?

I'm not even sure what the rest said. But please, stop making stuff up. Guys searching and reading this don't need any false hope.

-- Joe

jag327

This is so funny, any way the specs are the test sheets from the afr heads, man people do your on shopping around and talk to people that race the heads. For what I paid for and the flow - rate we thought the hp would be around 460 hp out of the motor. I don't play games, Any 1 post number the only way to no for sure is to be there to test the heads your self. Some heads on the market to do not meet there specs this is true - Your telling people that these heads suck when people are using these and getting good numbers, For what the cost and nice street rod mild drag car they work. Some people can't spend $1200.00 to $2500.00 on set a of heads. I will type again AIRFLOW
RESEARCH HEADS 210 runners these heads I paid for was $1850.0

intake valve lift at ,400L - 240, 500L -271, 600L - 279,

Exhaust valve at lift , 400L - 180, 500L - 198 600L - 210,
This is from the flow sheet that came with the heads.
The valves 2.08 / 1.65 Witch I had these heads 1.5 years and just sold them
3 weeks ago.

I have flow number from about 18 others set that I had tested at the machine shop with in 5 year time frame.

For what I was looking for out of the motor and to save some money to they
work for me and just like they work for others.

People way the pros and cons and talk to people that have the heads on a motor. AND RUNNING THEM like I did. I'm 48 years old I don't play games like some people I see. I would never call some 1 Lie when the are running the items. They may fit your needed and may not.

And there write up's on the heads I guy posted 1 in this forum if go back to the front almost. And there's more on the net ok for some people enter net.

The the procomp heads hit the market back in 1999 from what procomp told me over the phone. And there was some bad casting that got to the market. From what I was told they clean house.

The smaller heads 190cc the numbers was kinda low but you still can bolt on ago and get over 450 hp base on your set up on a small block chevy.

I have 2 set of procomp heads, 1 set is on L98 350/40 tpi motor, the other is on 65 327/30 over motor.

It's nice when people can post what they have used whether it's good or bad.

The Lie thing, funny I'm using the heads on a motor, I think maybe I show no something base on me using them.

This was from Skip White ebay add
The 58cc procomp are actually the least flowing version, and the reason is because the chamber shape interferes with the flow curtain.

The larger chamber procomp: I thank you should call procomp and ask about what Ship white place is his ebay add.

The heads the older 58cc some could be clean up if needed, Around the time I bought my set they was clean needed nothing

After I talk to procomp, and check the net or enter net forums more I bought to sets
and had them check out again by SUPERCAR AUTOMOTIVE like I have in the past.
And they needed nothing and flow very good numbers. Like I said.

Sorry but I have to chime in on this. Let's just settle on the facts. Too many people want to lie and make up stories to justify their decision.

Pro Comps are cheap foreign made heads that seem to have okay flow that can produce more HP than stock heads. Long term durability is questionable. Quality Control is hit or miss as mentioned by many all over the internet. In the Marketing world, this product would be your low cost provider. They plan on making the product as cheap as possible and selling as money units as possible to make money. These are made by the same people who put toxic chemicals in baby formula. Do you really think they are using quality materials?

AFR, Brodix, etc are top name brands who consistently produce A+ quality items that outperform cheap competitors. Long term durability is proven. Only top quality materials are used. The sell for way more than cheap competitors but sell less units. On the same engine they will produce dramatically more power than cheap competitors and is overall a premium product.

If you are selling used heads, AFR's will retain most of their value; whereas you would hardly be able to give away Pro Comps.

There are many people on these boards who depend on accurate information. By telling them that Pro Comps are good heads is irresponsible until they are proven and have long term durability like their competitors. Today, they DO NOT have that track record.

"Too many people want to lie and make up stories to justify their decision."
Lie??? this site http://wengines.com/flowdata.html has some more flow-numbers collected, he charge $5 to flow heads on his flowbench and post them on his site to help people choose the right head for their engine. Procomps flow pretty well. And he has no interest in making procomps numbers any better than they are. And I say it again, its very strange that a port that looks so terrible as Joe says can flow like it does.

anesthes

iTrader: (12)

It doesn't flow well. We've been over this. I'm not arguing with you anymore. We know why you bought them, the same reason lots of people buy them. THEY ARE CHEAP.. That has been explained in detail by you.. I'm not out to convince people those heads are not cheap, but I WILL NOT allow you guys to try and convince someone that they are a great heads and all they need to do is spend $600 to run 10s.. That is absurd propaganda. I'm sorry that good stuff costs tons of money in your country. I feel bad, I really do. But cylinder heads is one of if not the most important part of a performance build, and to skimp on that makes the whole project worthless.

-- Joe

jag327

Joe for 1 the lie thing should not been said at all you don't have set of the heads. I never said buy the heads you will 10s every 1 no's it take more to make a 10s car. I said people in MD VA are running the heads on a few motor and getting good numbers 11s 10s 9s and few 8s at the track. I no people are better than that to thank just having the heads bring 600 hp funny.

Now my runners exhaust port was clean - I SAY AGAIN CLEAN NEEDED NO WORK WHAT SO EVER, And was check out buy Supercar Automotive.
If you need there number just let me no.

For the money they are good heads and there are write up's in few Hot rod type magazine say - they are good heads.

No they are not the best flowing but they do flow better than some on the market. And people are buying them not only because the price is low but learning they can get some good hp numbers out of the heads on build up motor.

And people if your looking in to the heads check other forums and talk to people that run the heads on a motor. I sold my afr heads because I could get the hp I was looking for out of the procomp heads I have now. And save some money and put back in the car.

I race at - Summit Point Race Way in VA., Budds Creek Race Way, Cecil County Drag way,

pic of 327 motor with the procomp heads


84 mazda 372 mopar motor 727 tranny Dana 60 rear - I think, I should no a little something about cars.



I will say it again I have bought heads that did not flow base on the spec sheet that came with the heads, and no I few others guy's to, had to have the heads re-work.

I will say it again people are buying procomp heads and running them on the track. Even at few car show we seen procomp heads. I will not put a item down when it is work for so many people.

Joe do you have set of the heads can you tell us how the work for you.

Some heads you buy now come from over seas, And base on me have a pair of the heads, The number we got - I'm very happy. And in other forums people are happy running the heads. I don't thank it's irressponsible when I have a set and running them. When you have hot rod type magazines saying they are good heads. For me they are good heads I'm getting what a was looking for and a little more. I'm very please with heads on my 327/30 over motor. I have set of canfeild heads, Brodix 1x heads, and few cast iron heads they are good heads. When I 1st started seeing the procomp heads was around 03 but stay away from them until I started seeing more and more showing up on cars at the race tracks over the years and the numbers these cars was running with the heads. So the heads has been out for sometime. Just like here in - Third Gen, I look for all info good and bad and other forums and talk to people who used the heads and race them. I took all the info in everthing good and bad - bought 2 sets and had them check out at a TOP SPEED SHOP I no they will do a good job. The machine work was good the runner was clean they came with 3 angle valve job 600 lift springs. Both pair was flow tested and the motor was dyno after 500 miles. The procomp head was clean. If I can't say they are good heads then I'm in the wrong place , I'm not going to let no 1 say something to me when they don't even have a pair on a running motor. Say I'm a LIE... When I'm Telling you I have 2 set dyno flow test and drag racing them on a motor. Like others now people are looking for people that running the heads and machine shops that work on them.
That the best info you can get. Not some 1 being told the can't say they are good heads and flow good, this is wrong...

I forward this forum to the speed shop and I call him to see if he would give his input on all the heads they rebuilt and sold and about the procomp heads that been showing up for about 6 years in his shop. He may find the time but like me thought this was funny.

Other forums let you talk about the parts you use whether it's good or bad.

jag327

Man look like my chevy S10 L98 350/40 over

jag327

I will say it again for the last time my heads was check real good they was clean - all ports clean.
no work needed at all, it's really that hard for people to see other people - buying the procomp heads and running them and make good 1/4 mile times and making good hp..... something wrong here...

http://www.musclemustangfastfords.co...hp_stoker.html


All you have to do check some the other forums people are running the heads. And there more info than the link you sent.

These is other flow rates on the enter net all are not that same.....
There's another flow rate that was even lower the 1 you found.
Higher flow rates to....

But any way I don't have to LIE it's a - fact


Pro CompAirflow Data: CFM @V 28 INS. As-Cast 190CNC 215LiftINTKEXHSTINTKEXHST.10059476353.20011685130102.300167126182139.40021315723016.500241171264186.600251176291198.700258180303205

Compared to the as-cast 190 cc heads, the CNC-ported 215 heads offered more flow everywhere. The CNC version improved the peak airflow by 45 cfm on the intake and 25 cfm on the exhaust. More importantly, the flow numbers improved throughout the entire lift range. While more peak lift flow is good, more average flow throughout the lift values is even more important. Using the power versus airflow formula (HP=airflow x .257 x number of cylinders), the CNC porting improved the power potential by 58 hp over the as-cast heads.

We can talk flow numbers all day and I and I guess lots of people stare at and think that flow numbers are all that matters. This is how it went in the real world. The engine-shop that I bought my heads from dynoed a 383 yesterday with 6,0 rods procomp pistons, bore 020 and plain 210 cc PC3003 heads, hooker headers, 670 holley, camshaft partnumber lunati 60104, intake Procomp pc3021. He had it up to 5000 rpm but couldent go higher because of the belt or fuelmix or something. I dont remember what he said, BUT it gave 451hp@5000rpm and that cam should go all the way to 6200 I when its tuned. right? So how much more will it produce at 6000-6200rpm? 60-70hp? It will shure put down over 500hp maby 510-520hp.I ask you again Joe Is that bad for a set of heads that costs $600? and I think it also means that the heads doesnt have to flow like AFR Comp to put down some good numbers. Now I'm only waiting for wildjyoung to call me a liar also. I dont care, you use what you want, and I will use what I want, but you cant prevent people to share their expierience on Procomp heads and also calling them liars because the shared information doesnt suit you. I think I know what the problem is. You feel a bit cheated inside when we get about the same hp as you getting but we paid a fraction what you paid.

My Procomp heads has 2.05 sq/in and the port velocity are a bit over 300 fps

anesthes

iTrader: (12)

What was the flow chart results for yours again? 195cc?

2.05 sq/in at the choke point is reasonable on a 195-200cc head.

I calculate velocity by cubic feet per sq inch. It's a lot easier way to compare heads.

Okay, you're right. Your allowed to use whatever you want just as I am. As I stated previously, I hope your heads work well for you and you are happy with your purchase. However, that being said, I spoke to many people before I made the decision to purchase my AFR's. These were professional people who used these heads on projects and raced them. The vast majority said to save up and buy the premium heads. Overall, I have a little over $15K in my project. If I would have gone with comparable Pro-comps, I would have saved about $400. For me, saving $400 is not worth the risk of using a "cheap" head. Saving $400 would have risked a $5000 motor by using sub-par parts. On top of that, it cost me $400 for a premium head that will always produce more power than a cheap competitor. I do not feel cheated one bit by Pro-comps or any other head manufacturer.

As members of this online community, it is important that we provide accurate information. Posting on this board that a $550 set of Pro Comp heads is just as good as AFR's, Brodix, Canfield, etc is inaccurate.

I would advise anyone reading this thread and using it as a resource to purchase heads to carefully do your research. Read everything you can in and outside of this website about how to select heads. Use http://grumpysperformance.com as a resource as you get accurate unbiased information. Your heads are one of the most critical components of your engine so select wisely and do not make your selection based upon 1-2 peoples opinion.

I dont think I have posted anything about procomp are as good as AFRs qualite What I'm trying to say is that if you dont have the money for AFR, Procomp is a good alternative to make good power, and I have seen so many examples of that. And for me the last 20hp isnt worth $800-$900. What makes me angry is all the so called experts. Who can judge them only from what country they come from and I'm shure that 90% of the Experts has not even seen the heads live (I dont mean you Joe I'm shure you'v seen them). But they can make comment like chinese junk, etc. I dont think thats fair, Look at them test them if you have the opportunity and then make a comment and have in mind that they cost only $550 or something I think it will be a little different after that.

anesthes

iTrader: (12)

I have no problem with Chinese parts. Or any other country.

I also have no problem with procomp heads. I think for the money they are good for a specific application.

I wanted to pick up a set of procomp 220 CNC heads, and do some work on them. I was told by Skip white himself, there was absolutely NOTHING I COULD DO to make them flow more. (this is the CNC version). The problem was, for the test application I wanted to use them on I needed around 30cfm more, especially on the exhaust side. So I couldn't use them. Keep in mind, the price on the 220s is not cheap assembled, it's within a few hundred bucks of AFR 195s which actually flow more than the CNC 220s.

For guys with 350, 400hp street cars, budget cars with stock bottom ends the procomps are fine. But I also, don't want people to get the idea in their head that for $600 they can buy procomps and outrun cars with AFR heads, Profiler, etc. I posted the tech, the charts with flow comparisons, velocity. Even explained a little as to why it's important. A lot of the responses, from jag for example were hard to read and just saying over and over again his friends use the heads. (I think that is what he said?). YOUR argument to using them has been stated and understood. You are getting TANKED on fees buying from the US. We get that.

I use AFR on my builds and friends builds because my cost for AFR is cheaper than what Skip White sells CNC 220 procomps for. Believe it or not. And like I said, I don't build anything less than 500hp (unless it's a plow truck) so the majority of the procomp line doesn't work for me.

jag327

This is nuts no 1 said the procomp heads is better afr, brodix, canfeild heads, I have a set of the brodix and canfeild heads with me right now, Why are you so biased when it come to these heads procomp. It's clear people are buying them and running them. I thought this forum was about people - who had experience with procomp heads, Who can tell the bad things they may have went through. But when it come to the good things about the heads you like to beat the procomp heads up.


Will these heads procomp can make 450 to 550 hp in Small block chevy can you say yes. Are peolple running them can you say yes, Is there any hot rod type magazines saying they are good heads can you say yes. - wildjyoung can you say yes 3 times


Wildjyoung
What most people wont no is people who are running the procomp heads, the good and bad thing about them the procomp heads. Most people no by now there on motors and people are using them. So to help people, people really would like to no the problems with the heads and the good things about the heads. This will help people out now.... people no there better heads out there. When your building a street to mild drag car some people don't have the bank roll you may have. And if they can get 400 to 550 hp out the procomp heads and save some money at the sametime. This is a good right.

So if more people come to this forum can you please let them say good things about the heads to, please please kind Tech Sir, along with the bad things.

Thank you

"O" the heads I'm talking about are the 210cc CNC cost me complete $525.00 a set is what I paid for with springs and valves.

Here we go again the heads check out buy SuperCar Automotive, And the shop guy that test them said they are good heads. There are beefy lots room to shave down, I was looking for about 450 hp motor what got was 523 hp at 6200 rpm small block. Like I said before, I had the AFR 210 2.08/1.65 valve heads I was going to put them on the motor but I started see more and more of the procomp heads on running motors at the drag strips and in some of the cars on running at the shows and talking to people. I sold the AFR heads and save some of the money to put back in the car, I'm very happy with a 327/30 motor making 523 hp at 6200 rpm

Lot of people was saying good things about them and some bad things like you have been and what I understand you have no experience what so every running these heads in your car.

I see now it's best for people to talk, to people who have the procomp heads on there motor.

You word the - the procomp heads down and I still don't understand why...

I'm using a set of Procomp BBC 320 heads with roller springs that I bought from Doug Herbert Racing. I gasket matched them to a Fel-Pro 1275 intake gasket. I installed the heads on my 13-1 compression,720 lift roller cam 496 and ran a 4.92 1/8th mile in an 1800 lb dragster. They come with Dart adjustable pushrod guide plates, so rocker arm alignment is not an issue. I am very satisfied with these heads and sorry if some of the guys out there spend twice as much on a set of heads but can't seem to out run my cheap set of Procomps!!

I just sold my chevy S10 with 350 40 over motor tpi set up. I'm keeping the 327 camaro. I would go with 750 cfm have it blue printed to your engine. For street use and to save a little gas 650 cfm this would be the smallest carb to run. I have ran a 1050 cfm 4500 holley on my car just to see if it would take it and run low end was a little slow but man after 3500 rpm all the way to 7200 rpm it pull very hard. I wish I had clock it at the track. The carb I have for my 327 is a blue printed 735 cfm and blue printed 835 cfm with this carb the motor pulled 523 pass 6000 rpm.

Ignorance is bliss.

Given the choice between those and Vortecs (the link to the design 3), I'd choose the vortecs.

But, I can't think of ANY combo I'd ever built other than maybe a stock replacement motor in a plow or tow vehicle that I'd use vortecs.

If you're going to spend money blueprinting and building a street/strip motor, why buy heads that flow 250cfm.. (if even)


I know what the guy is saying. But I'd hate to have someone mistakenly think that a pair of $600 heads are 'just as good' as AFR, Brodix, etc.

For a 350 hp motor they would be fine.

Why spend over $1500.00 when you don't have to. This what a lot of people are seeing now. Most people love hot rods and would love to build with top name stuff.
But don't have that can of money.

So this is where procomp is coming in to play. I till you another company parts are show up on cars over here MD VA at 3 of the race tracks wysco.

Ignorance don't have anything to do with this. It's buying what you can afford.

there's guy at speedunlimited the sale over 14 other types of heads, he bought a set of the procomp heads and ported them on a 383 motor dyno 6600 rpm 592.7 hp.

I won't even tell you the flow number's because I no how you guys are when it comes to people making good number with the heads.

Like I said before, can the make 450 to 550 hp in small block motor yes.

There's a right up on the heads where they took a stock junk yard motor 350 with the procomp heads a cam manifold and carb. made 450 hp....

This the company I buy holley carbs from, TMZ Products 1-586-365-9628.

They can blue printed to your motor. And the cost is the same as buying
a new holley....

jag327

Just a note to you joe they can blue print the carb to any motor, make's easy on people who don't like messing with jets.

The cost is the same as buying a new carb only it you buy the carb from them.

I wish you was local, I would love for my cheap heads and car meet you at the track.

Gentleman, I believe this has gotten out of hand. Honestly does it really make sense for a moderator to be so argumentative over a product. All people are saying is what they know from experience from the product. Perhaps some made some audacious claims about the performance of the product but that always seems to happen. I don't see the need to over clairfy the risks of buying parts that are considered cheaper and have "unproven" performance in both power and quality.

I believe it comes down to the customer to have a cognitive thought and be a smart shopper. Being as I'm a salesman, it is my duty to inform the people on the product, if it seems too be lacking in information, I offer words of advice and nothing more. Again I believe it now falls into their hands to make a decision based on the information they have been given as a buyer. I do not proceed to pound my own opinion into them, for it is not my job and it is not my money. I offer my advice and say it once and claify if they ask.

I really don't see the need for this contest of who can discredit who for what information they can find on the internet. I base my opinion off of experience with the product and if I have none prior, I ask those who do. It is for that reason that I decided to go with a set of procomps for my Camaro due to the fact that im not building anything monsterous, in which case I would go with a higher end head. Being a salesman, I know that there is a price point for everything and everyone, this matches my price point.Also being as I am also a consumer I know the risk envolved and the limit of the potential of these heads, they will work for my application.

I came to this decision doing research and evaluating what I need for my price point. It is not my job, nor anyone elses to think for others, regardless of what it is we think is best. It is their decision and should be left to them, it's not my issue what they do as long as I provided the information that was required of me when asked, plain and simple

I know that this has been a long Thread, but I just wanted to post an update! I have the car all back together now, the car runs strong. The only thing that I am now having a problem with is that it idles good for a few minutes than it drops down, stumbles a little, than the idle will go back up and run ok. when I drove it a few days ago, there was also some poping through the exhaust while still in gear but slowing down. I put in a new distributer due to some rust on the pickup coil, but there was no change after replacement.

I am really sure that It would help if I ordered a chip for it! does anybody have any sugestions?

I'm not sure if this will help anyone but here goes. After reading alot about the procomp heads I decided to go with them just for the price. The crank I'm using is cast so performance wasn't a big deal for my engine. Didn't want a lot of power just tired of my old engine. Picked up a used short block 383 that seller told me was internally balanced and cast. It didn't add up at the time but for $450, was good for me. Had it balanced, put on the p/c heads and intake and fired it up. 4500 miles later its was still using oil and fouling plugs. I suspected intake and believe it was. After removing the intake the second time and cleaning everything up I sat the intake back on the block, yes block. It slid over and left nearly an 1/8 inch gap between intake and head. With 1/16 inch think intake gaskets, well it didn't seal very well I believe. Somewhere I read that either 1206 or 1266 gaskets should be used with these heads. 1266 are 1/8 thick and I believe the port sizes are different as well. I'll let e-one know how this works. Other than that the heads seem fine. I'm not a mechanic so a real one might have seen this sooner. Can't blame, supplier they were great. Also have some other parts of their's on the engine too. We'll see what happens!
