HELP! Which heads (AFR 165's or Track Heat's)?

[Fri Guy]

AFR 165's or TF Track Heat's??????

It's pretty much a stock 306 bottom end with about 30K miles. Pistons are not notched so I can't use the AFR 185's. I have a E303, Typhoon Intake & all supporting mods like injectors, TB, MAF, CAI, MSD, full exhaust, etc....... My stang is only used as a daily driver & has never seen the track. Just want more power on the street. Suspension will be next after I get some heads & a tune. So LMK what you think!!!

I I have seen guys use 185 heads, it all depend on their cam. E-cam shouldn't be a problem due to not being .500 lift. Anything over .500lift should have pistons notched. But I am using the Afr 165 and I am happy with them and I have E-cam as well

Damn repost

 

[Fri Guy]

Have you had it on the dyno yet?

Have you had it on the dyno yet?

No! But I whopp some ass in the car though. I have more than just AFR165 and E-cam.

there is no wrong answer. they're both great heads. personally i would think the trickflow is a better bang for the buck. they are a 170cc intake runner.

As an owner and frequent abuser of AFR 165s, I can say with confidence that on a N.A. motor you will not be disappointed one bit if you decide to run the 165's.

I'm completely satisfied with the AFR 165's.

I'm very satisfied with my AFR 165s. So is a buddy of mine.

Other friends with TW's are satisfied with theres as well.

I personally have the afr 165s. They work great for me, but either would be a great head.

However, be careful if you go with used heads. I bought a set with suppossedly 5k miles and the valve guides were wore slap out. That right there basically wasted my savings of buying a used head versus new.

In before the move! (not tech)

I have TW heads, I'm happy with them. Either one will work well and a search will find you probably 200 other threads that ask the same question.

 

[Fri Guy]

Thanks for the help!

ok heres a small OT question ive been wondering about.

how are you guys getting a 306? just boring the cyl for more displacement?

 

[PJB]

A 306 is a 302 bored 30 over

 

[superspec]

A 306 is a 302 bored 30 over

thats what i figured. so a set of heads for a 302 still work fine then?

 

[Fri Guy]

Yes

 

[Sicarius428]

Both are great heads. You won't be disappointed with either one. Bang for the buck the TFS heads are unbeatable but for out of the box the CNC porting on the AFRs are beautiful. The one nice thing about the TFS heads is you won't feel bad getting them ported later on if your application changes.

How much power can you produce, with the 165's assuming you are running boost. I'm kind of building an intermediate engine at the moment but eventually I'll be running a DART 347 stroker with mad boost. I want a head that can handle about 7-800 hp. and I don't want to have to buy them twice. So if I get 185's will they be doggish on my NA combo until I build the big daddy later on?

 

[Fri Guy]

From what I have heard, the 185's would be good as long as you have your pistons notched.

I have the AFR 165s but they are the competition versions with heavier duty springs, more porting from AFR, and 7/16 studs. They are supposed to outflow the "standard" 165s. The car should be together very soon and on the dyno. I'll post when I get her runnin'.

Here's a ton of pics of my buildup so far. Check out the ports on these heads!
