I hate to get this old thread started again
but I am thinking about replacing my FMS GT 40 X heads ( with FMS 1.6 alum rocker) with AFR 165s on a mild 302 with an Air Gap manifold, QF 650 double pumper (built by Brent which really woke it up), MSD, either a E303 or B303 (not sure what) cam and a stock bottom end. It pulled about 280 RWHP a couple of years ago with a crappy street avenger.
I don't want to do any mods so I want to stick with the 165 and not go bigger with 185s or TF 170s since I am concerned about PTV clearance. My questions are:
What 165s should I go with? The 1399s, 1402 or the pedestal mount 1472? I understand that if I go with the stud mounts I would need new rockers and hardened pushrods. With the 1472s I could reuse my old rockers and pushrods?
The engine has about 8200 miles and runs good. Just would like a little more kick. Who knows, if this doesn't work maybe I'll just get Brent to build a new engine.
Thanks.
