pro comp big block heads
when I get the heads in ill post pics,they ported them and have roller springs in them for 750 lift,as I have a roller cam,i will have to run a indy intake as they been ported to max wedge size
you all might be interested in this: we flowed my procomp victor knock offs.
we back cut the intakes a small amount, made 10 cfm dif. @ .200 , and .400 lift,
everywhere else was about 2 cfm. they are standard port cnc`d , flowed 350 on the intake @ 600 lift. my street roller is .620-.628-before lash (.016-.018 lash)
I`m well pleased w/ them, altho we changed the retainers and keepers for some compcam parts. it appears the exh. valves are s.s., and the intakes are low grade s.s.
the only thing I don`t like about them is the threads aren`t helicoiled, but the bolt holes are very deep, so I`ll run the longest bolts bolts possible in them w/ anti-seaze and torque them carefully, don`t expect a problem, unless a guy had to torque and re-torque over and over. would like to run my new victor intake on them, but afraid I can`t get the carb under my 6-pack scoop. it stuck above the fenders when I had it all dummied up, w/ no air filter. currantly have the eng. on the stand w/ a torquer 2 on it.---bob
