Greetings Ramey & all; NICE parts. Have you decided on a cam yet or did I miss that post? And what compression will result from all those fine parts working as a team? I have a 406 " SBC with some 1996 AFR 190 runnier heads that have been ported out to 200 cc's & the low end torque is SERIOUS! And you will have more compression &18 more inches. Could I ask you to take a picture of the drain back holes at the ends of your AFR heads. The reason I ask is that use to be the weak design area of Air- Flows product, very small! But you also have to keep in perspective that many of the engines that these heads go on have lifter galley resistors. I didn't want to restrict oil to my lifters so I went with Smith Brothers reduced oil hole push rods. That helped a lot, so please keep that issue in mind when building your engine. I think that over the years they (AFR) have increased the return hole diameter. Back to cams, consider the Comp 4 pattern Hyd lifter cam. The technology - engineering - development far exceeds any single or dual pattern cam available. Mid range gain is Serious with these cams. So keep an eye out for too much oil up in the valve covers & GOOD luck wish I could help, Ole' Bob.
