I need help guys. Im clueless when it comes to heads. Im gonna install a Edelbrock HiFlow intake along with a set of SLP Siamessed Runners. The intake is for the 86 IROC that I have. So which of these heads would you prefer to buy IF you have an intake like mine?

 

I ran AFR 210s on my 350 with great results.

 

210's are quite large for a stock 350, peak power might look good but low rpm power will suffer.

I think AFR195 are a step in the right direction. Also In my opinion you cant beat the price/performance of assembled Brodix IK200's so those are what I recommend.

 

GMs 350ci fast burn heads are 210s. The 346ci LS6 uses 210ish cc heads.
210s are NOT to large 4 a 350 at all. I'm soooo sick of hearing that myth.

 

For TPI its abit large...you wont ever get into the rpm range that the 210's can support on a 350 motor.

On stock bottom end with mild TPI on top, figure a mild 212/218 or 218/224 type cam, i'd go 180-195cc's and no more.

 

Low end will take a hit, with a stock 350. You need something with a slightly smaller intake runner to take full advantage of the power curve. Of course with a Modified 350, higher C/R, more agressive cam, with a single plane and/or power adder 210's would be fine. Never said they wouldnt work, just not needed to make the numbers that a 195 runner can make.

Fast burns have a different design anyway, AFR195's out flow them.

 

uuuuuggghh

 

Some people just don't see enough builds on a daily basis to see how true this is. I know, because I do.

 

So I take it that the skip white heads are not a good choice.

 

x2

 

195's are going to make for a stronger feeling motor with tpi. Flow numbers are not everything. I dont follow the AFR bandwagon though.

 

I guess English doesnt cut it. Let me try something else. Quero usar unos cabesas para mi Camaro puero estoy un poco confundido. Si aye algien que me puede ayudar, te lo agredesco. Gracias por no hacer mi pregunta mas cumplicado como los otros personas ablando de otra cosas.

 

Thanks for hijacking the thread.

 

I dont see a hijacking...you asked the open question on what heads and you got a bunch of opinions.

If you have more details on your exact motor build, compression, hp goals, cam specs if known, etc, you can pick a head to fit those needs. Only information given is edelbrock TPI based system...thats a good indication of rpm range/power goals as it sits but more information is helpful.

 

Can you be more specific about these results?

 

What the!!!!!!! Damb co-workers. I left my iPhone unattended. I didn't put that crap or the Spanish. Esos cabrones. Any ways, please forgive my dumb friends. Cool man. Well to give you a quick run down of my setup, well it's pretty much stock. In a few months, this is what I'll have in my IROC, Edelbrock TES headers and y pipe, Edelbrock hiflow intake manifold, siamese SPl runners, LT1 cam, and no cat. My MAIN issue is that I wanna junk my current heads which are the swirl ports (heavy duty trucks) and get some good aftermarket heads. Thanks for the few back everyone. Keep em coming.

 

Small cam, I wouldnt go any bigger than 180cc stuff like AFR 180's or Darts 180 platinum pro1's or Brodix IK180s. Anything bigger is kinda a waste but can still work. Guys have shown good power gains with 195's on stock cams. Just isnt optimal.


I'd swap cam too along with a set of heads and let it eat. Pro filer 195's or AFR 195's would be my choices.

And your exhaust system could be updated...TES stuff isnt that great

 

Exhaust replacement = noted
What if I where to invest into a Comp Cams computer controlled cam? Summit racing told me a while back that they had a cc comp controlled cam that is a step up from stock.

 

I agree with above. No point in buying super-flowing expensive heads. Just about any aftermarket casting in the 170-190cc area will give the same results with your combo. I would however stay away from those Procomp heads on that site you linked to. They are junk. You may save $200-300 buying them but you risk destroying your engine or having other problems down the road. Not worth it at all.

 

Cool. Thanks bud. So the Skip White heads are now out the window. Time to research the heads that you and Orr89RocZ suggested. Again, thanks guyz.

 

I'd step up a few steps from stock and let it eat...it will require a tune tho. No reason you cant make decent power and still drive exceptionally well, just need tuned and thats the hardest part if you cant do it yourself or have a local friend to help. Its not like the LSX game where you can take to just about any local shop and have decent work done to get you close. Most major cities have a shop for lsx stuff that can tune them. Dont see that with thirdgens.

 

I'd just better not say anything at this point..
I've done things with my cars/motors that aren't approved by thirdgen.com (and that includes running over motor parts)

 

I too have been keeping an eye on the aluminium ProComp heads assembles by Skip White.

Skip White seems to know his stuff and they seem like a great deal.

 

Regardless of that this guy seems to know, Procomp needs to be run out of business. Look at this to get an idea of what kind of company they are: http://www.yellowbullet.com/forum/sh...3&postcount=10

 

Just checked out the shoddy work. What if the original owner did that hack job but didn't fess up to his friend? I dont think that a semi known company would do such a poor job. But then agian, if procomp products are manufactured in china, well that opens up a new can of beans. None the less, that is electronics and not a mechanical aluminum block of aluminum. If there is supporting evidence of bad to extremely poor performance and functionality towards procomps heads, then I would further understand. But 1 picture of a hack job doesn't mean that the company works dirty. Maby it was altered after it left the factory. It all boils down to he said and he said. But I'm gonna investigate procomps heads to see if there is infact any proof of being a bad head.

 

But why support a company that blatantly steals other company's products and has them made in China using questionable materials? Is it really worth saving a few hundred bucks? Cylinder heads are a vital part of an engine - why even trust such a shoddy company with something so important?

MSD actually sued Procomp and won over their copied ignition boxes. I wish more companies would do the same.

 

They got sued? Nice. But that's not of my interest. I'll consider your opinion. But not everything that a company makes is half @55ed.

 

I guess I'll chime in here. In my opinion, the AFR 180 head is going to be your best performance. AFR has really done their homework on the Eliminator series.

I'm running Brodix RR200's on my 406 and I have no complaints, but if I were buying a set of heads today, it would be AFR.

 

I second the AFR 180's. That's what I have.

 

I like AFR's always did but for the money BrodixIK series are tough to beat especially their cnc ****. Something to look into.

I don't know much about skip white stuff but if have heard bad things across the board about their products. Intakes port match super poor, heads have excessive cast material that needs to me taken down and smoothed and metal shavings, HEI distributors are direct copies of msd street fires from a chinese company and have sub par quality. The list goes on.

The only thing I have bought from them was a aluminum throttle cable bracket. The kit came with crappy screws that had to be replaced, the material was cast very poorly, many rough edges had to be sanded to fit perfectly. The paint was horrible I had to blast it and respray it black. Something so simple, that's hard to mess up they did a pretty good job messing it up. You get what you pay for put it that way.
