The cam is the .528 solid purple shaft. 1.5 ratio Crane ductile rockers. 5/16" Crower push rods. The pushrods did rub slightly, I used one .015 " spacer shim on each side to achieve clearance next to the intake runners.The springs are Comp 26918-16 , recomended by Comp. 1.8" installed height. Where I exercised some judgement on my part, was to use two .030" shims under each spring to increase my seat pressure from 125 lbs closed to 147 lbs closed. I now know this is not the correct way to achieve more seat pressure. But,by my math of 1.8" installed height -.502 net valve lift, -.060 shim height and a coil bind height of 1.10" I'm still left with .138" clearance from coil bind. I'm really hoping those shims are not my problem. I have visually confirmed that the springs are not close to binding as well.
