I've built Chevys in the past and on a Stock build I would not be concerned. This is not a Chevy the valve lash was off, so I ordered adjustable push rods. My valve stems are not the same length, they very about .060. I ran the pre-start compression test Low cylinder was 115 (a bit low) and the high 140. With the compression It should 9.4:1 be, I should see 140 pre-start and 160 after the ring seat. What I'm concerned with is the range "25". Should I be?
