all stock around 135 to 150 but if they are all within 10psi of each other than its probably good but bigger cams can make compression tests lower fyi

if the bottom end is fine and has no leaks. perfect compression i would say is 160+ . my buddy finished his rebuild with stock internals but with 1.2mm hg and compression tested 170
