RE: what heads for best performance?
ok ive been lookin at trickflow and likin there heads but i guess what i really ment was what numbers would work best and match up with the cam best. like chamber size and intake size numbers. cause im afraid if i go too big it might not make it work right.

personally i would get afr 165's. great head for your combo. i would also get rid of the cam for somthing that wasnt designed in the 80's. a lot has changed in the last 20 years in the world of hyd. rollers.
with more engine i think some afr 185's, canny's, or tf track's would do well.

as much as i loved my afr 165's im going to have to say they are too small. they were fine on a 302 with the stock cam but with my 331 they are horrible. get the 185's at the very least.

i see you want your flying powers,research afr, edelbrock, and trickflow's website.
You can get an average of 350-367 hp at the flywheel with the right HCI combinaation, thats like 280-310 to the wheels after drivetrain loss and emmisions etc.That plenty of get up .
A stroker is a whole other issue, and a 80-100hp jump depending on displacement and tuning
getting into my engine on several occasions for power upgrades, I must say take your time, save your money and do this once if you have to. Took me a few years
