Are the AFRs worth the extra $$$ compared to TEA Stage 2 CNC ported 317s on a 370" w/88mm turbo?

I'm not sure what "TEA Stage 2 CNC ported 317" are, but sounds like a stock casting with some work done, if thats the case i would do the AFRs or if you can TFS heads because the deck is thicker... Hope you plan on running studs.

Whats the price differance and your power goal?

The 317s are ported stock castings from total engine airflow that fall a little short of the AFRs in the flow department.

I want to make enough power to push a 3800lb truck into the low 10's and the price diff is $1000

not worth it. in my IMHO

I have been thinking the same thing. The ported 317s sound like a good head at a great price and I have seen alot of cars with them making great power.

Cant you do that with stock unported 317s? 3800# is pretty light for a truck!

That is the weight I am shooting for. It can be done. I might go with stockers, I am in the planning stage so I look at all options and try to go the best way I can with what I got to meet my goal.

It depends on how much boost you're wanting to make. As has been posted, AFR's and Trick Flows are thicker, and so are the newer RHS heads. Here is a link to them. http://shop.brutespeed.com/RHS-54302...-RHS-54302.htm Bob

^^^mocking fail!...IMHO = "In my honest opinion" who cares if he said "in my" first.i think people understand
To the OP...I wouldnt spend the extra cheese....Those 317's will make great power. "IMHO" I would def strap them down with some ARP studs instead of bolts. The deck surface will be thinner with the 317 compared to AFR, TFS etc...
I believe you will be golden with 317'sand 1k extra in your wallet

If $1000 isn't a big deal for you, get the AFRs. If money is tight, 317s can get your there as long as the rest of your setup on. Use a good MLS gasket and ARP studs. Keep an eye on back pressure as well.

I plan on running studs and when the time comes I a might not have the extra $1000. i will probably upgrade later to AFRs or trickflows.

u get what u pay ,, i say go with some heads that have more thicker deck then stock castings

You will make more power at a lower PSI with the AFR or TFS head, and if you need to turn up the boot later you will have a thicker deck to work with. Spend the extra money the first time around and you won't have to buy parts twice.

I think the 317's will meet your power needs/goals quit nicely and if I was you thats what I would go with, but, if you think the 1k wont be an issue, ^^^03supercobra is right, do it right the first time.

I agree with this statement fully. BUT, you are trying to get a 3800lb truck to the 10's....I really dont see and problem to do that with 317's at all. There has been several to reach 800-950rwhp on lightly touched 317's. Yes the AFR or TFS head are the way to go, but are they worth the extra 1k when you can hit your goal easy with the 317's? That is the question to ask yourself. Now as for a power goal, there are several reasons you need a thicker deck. cylinder pressure, boost levels, back pressure, what type hardware you use, it being a 4 bolt head is even enough. I belive you can drive that thing all day long iin the 10's with 317's and spend that extra dough on good suspension parts
This sums up my ranting! lol
