AFR 180 Heads
I have a modded L98 with a few mods, stealth ram, TPIS ZZ-9cam, etc and currently run Vette alloy heads, mild porting and stainless valves, stock size. Would I see a big bennie in going to the AFR alloy head? I curently pull around 310 at the wheels!
Thx

Re: AFR 180 Heads
Oh yes. AFRs flow a lot more than the old Vette castings. Can't say how much the mild porting might have improved your heads over stock, but they're still not likely to be the equal of a set of AFRs.
So far my success with AFRs has been 100%. Everything I've bolted them onto has gone faster, sometimes by quite a bit.
