G Gibbs:


Do not get the assembled heads, the parts they use are junk. Intake flowed 335 cfm at .650 lift, I don't remember the exhaust. 2.19" intake, 1.75" exhaust valves. Cam is 258 / 260 @ .050 duration, .619 / .626 lift (custom ground by my builder). 10.8 to 1 compression, Holley 950 HP carb. Also using Edelbrock intake. Made 585 hp @ 6,100 rpm and 570 ft lb torque @ 3,750 rpm on preimium unleaded. The trick is all in the heads and cam. Car idles at 850 rpm alll day long and never goes above 195 degrees in stop and go traffic when its 90 degrees out. If I missed anything, post more questions.
