i am wanting to hear suggestions on which heads i should buy for my setup it is in my signature also about to hit it with a 150 shot

 

The best ones you can afford. Heads should be the single biggest investment in your engine, they are what make or break the power potential of your engine

Whats your budget?

 

I would lean toward using 200-210cc heads from AFR.

But like mentioned, the best that you can afford.

 

money is not that big of an object i dont mind spending 1,500 dollars on a set of heads i just dont want to spend and insane amount this is a weekend cruise car

 

Then I have your answer.... $1250 including shipping, cheapest place to get em. I ended up paying $1600 for mine after some upgrades but the difference was tremendous.

AFRs are the only way to go, all my vehicles will have them....cept the wifes Saturn

Look epecially at low to mid lift, and the huge difference in exhaust

Edit: I know they dont make 190s anymore, 195s are basically the same...

 

Nope . There are other options. Like these for example:



These flow well above the level of the AFR 210s even.... And are considerably cheaper.

These are M2 CNC ported Brodix Track 1s. And I paid slightly more than $200 more than you and I had every upgrade available for these heads (Ti retainers, full CNC, custom springs/valves package, etc.).

There is life beyond AFR and it is good .

 

The CNC Brodix heads I have seen have always been ~$2200 which is out of the range of what typical guys want...

Where did you get yours??

 

Well $2200 is still cheaper than the AFR 210 and they flow better... But I got mine locally from a guy that is a Brodix dealer but does it mainly to get the discount for his own stuff and just sells a few things here and there at slightly more than his cost.

It does all come down to budgets like you elude to, but I have gone both ways with heads. The first time I went with Trick Flow 23* heads and they were fine but really had nothing to offer when I wanted to step to 400+ RWHP and a larger engine.... To me it just doesn't make sense to cut corners on cylinder heads..... There are a lot of other things that will yield little or no results if the heads don't get the job done. And a lot of those things can be added later on if all of the money is not available when the engine is being built (like intake, headers, exhaust, air intake, etc.) So if the difference in price is fairly minimal in the big picture I must say that it pays to spend it on cylinder heads.

Adding parts to an assembled long block is a lot easier than swapping heads...

I just always feel obliged to say something when somebody says AFR is king of all cylinder heads . They make good stuff, don't get me wrong - but there are other options out there. Dart also makes some awesome flowing heads but I don't know what they run for pricing...

 

True, about not cutting corners on heads. But I do think AFR is the best "Affordable" head out there right now, its also a prestige item. It also seems that everyone online has them, but it isnt that way around town.

Race Ready 210s are $1445 with free shipping

 

Plus the full CNC porting...... and Titanium Retainers.... and probably the better valve and spring package since that quote is for the base level ones....

When I was looking at heads I was seeing $2500+ for a comparable AFR 210 head to what I got with my Brodix Track 1s..... But they still didn't flow as well... And the Brodix had a smaller chamber size.... The Track 1s are flat out a better deal than the AFR 210s whether you are talking as cast, partial CNC, or full CNC.... Better pricing, more flow.

 

What online stores sell AFRs?

 

Cant Dart Iron Eagles be ported very heavily? They say they have thick walls for race porting. If you were willing you might be able to beef those heads up alot. Also Pro Lightning heads are cheaper but could be ported extensively to gain good flow. For a weekend cruiser and not a race car, that wouldnt be a bad idea. Any thoughts on that?

 

I would not recommend a head with over 200cc intakes for a 350 block. I recommend going with the AFR 180 head. You will need to have them milled to get the combustion chamber down to at least 64cc.

Don't get me wrong, the AFR 210 or Brodix Track 1 are good heads. Just too big for your motor.

I am using Brodix RR200 heads on my 406.

which afr heads would be best to put on a motor that's spinning up to 6000, 6200 rpms? the 180's or 195's?

 

AFR lists the 195 for rpms between 2500 and 6500.

 

yeah, and the 180's are good up to around 5500 rpms and the 195's are good up to 6500. thing is... my cam range is 1800-5800 and im running the hsr right now and i don't plan on spinng my motor up to 6500 rpms. the most i'll spin it to is around 6200 rpms. would i produce more power with the 180 than the 195, or should i just go with the 195's even though i wont be hitting her up to 6500? with the 180 i think i'd have more low end and mid-range power, and im sure i'll make power up to 6k, but with the 195's, i know i'd be making more top end.... i just wonder if i'd make the same low end and mid-range power, or would i lose a few horses that makes up for it in top end. thanks guys

 

IF your going to error, error on the small side. 180s will surely do the job you want them to do. I think youll have a winner with either set to be honest.

Read this article about the 180s, keep in mind they are the competition 180s though, not the race readys. Which adds $400 to the cost of the heads. But none the less it goes agains what most people think, big ci and 180cc heads. Still makes great power

my vote is for trickflow heads and price just because ten people are running them does not make them the best.and cylinder head companys pay magazines big money to say there heads are better do what you fill is best not what the other guy says.i am still running the first trickflows and they are still running price paid was 800 summit.

 

Trick flows are nice heads, but are still 195 cc heads. I would go with the 195's imo, cuz they still maintain good velocity at on small cube motors, make good low and sick high end powr, and have better flow capability than the 180's. If you want a 195 cc head, might as well go AFR to get the advantage of more flow. But for the price of AFR's, the extra cfm gain may not be worth it, only if you really need all of the flow it provides. I plan on trickflowed superram in the next year or so.

 

Says about 1300 bux for non CNC heads, now is that bare or assembled? If its bare then trickflow here i come.

 

Those arent non cnc heads, all AFRs are at least 70% cnc'd on the intake(competition is 100%)

You can get AFRs "as cast" but they are only like $800

So those $1300 heads are what everyone has, they are complete and ready to bolt on, with CNC

 

I c hmm, whats the max lift on those springs?

 

Looks like its bout .550, thats g*y, id want to be running closer to .600 (just because I dont want to get rid of my 1.6rr and have a cam with a decently high duration. Also I see that it needs guideplates, could I not use the guideplates so that I can continue to use my self aligning rocker arms?

 

im sure if you tell them you're running high lift cam, they'll put in springs that'll handle it.

 

When I bought mine I got to choose springs. They had basic coices though.... Flat tappet or roller springs.

But this is all meaningless as you should only run the springs that are made for your cam.

 

K when i order ill be sure to tell them.
