i like the tfs heads but you have to buy after market roller rockers for them which is more money. afr heads are pretty badass to imo. you cant go wrong with either head you choose

You can't lose with either. But I had both and I like the TFS pieces better.

No..you dont *have* to buy roller rockers for TFS heads, they tell you that so you will because with large lift cams, you have increased valve guide wear and imperfect valvetrain geometry..

It is just as much recommended to run them with AFR heads as TFS heads.



P.S. We've seen a bit more power from the TFS heads (most likely due to the 13* valve angle)

50/50 both are GREAT!! Flip a coin, Heads- AFR, Tails- TFS
there you have your choice.

I say AFR, my 205's made great power on my 346, and even more power and insane torque on my new 402. Gotta love being able to re use parts.

Buy a set of ET heads and do better then both.

I have never heard Tony Mamo recommend using roller rockers.
And there are enough AFR's out there running on stock rockers that if there was a problem doing it everyone would know by now.

Edit, here is an old post that has alot of good info.

Another beating the dead horse thread.

Not trying to be a dick, but you will find everything you need in past threads.

i heard that you dont need to get rockers you just need to shim the stock rockers and get a longer pushrod. also i heard dont know if it is true but alot of aftermarket rockers like to float at high rpm.

Just ordered trickflows from Vengence with the upgraded trickflow springs! They were the 220cc as cast for 1700.00 you can't beat that!
The Trickflows have a 13* valve angle so in order to keep proper geometry you need a set of roller rockers period, and why wouldnt you when you have 1700-2300 dollar heads. I wouldn't risk it.

Go with the trickflows you wont regret it!

Trick Flow HANDS DOWN, I want the Trick Flows and will get a set this year, in my opinion there is know other aftermarket head out there but thats just from what I have seen in person and my personal experiences.

newbie question

what are et heads?

ET performance, now Induction Performance, as Cary (guy that did all the design work and porting@ ET broke off and took the castings with him, to make the story short.

11 degree heads, and you don't need any special rockers or any of that to get the geometry right. I've been running a set for 3 years with stock rockers, and not a single problem.
