what is the most lift and duration that i can get away with without having the valve hit the pistons. i am thinking of going with 1.90/1.60 afr 165 heads any help would be appreciated.

alright dont quote me on this but with stock heads and pistons nething over .500 is getting close not much more can be used and the afr heads use same dimensions except on there race heads which have ports moved, raised deck hight ect maybe someone else can give u lift figures with afr heads

I have a B303 cam in my 95 GT, with 1.7 ratio rollers, which bring the lift to .51". No problems whatsoever, it sounds great, now I whish I had more
