Needing help with pushrod length and compression
Ok so I have a 370 with PRC Stage 2.5 LS6 heads milled .025 the heads are offered from 58-64 cc chambers and my receipt doesn't tell me which so I chose 58 to be on the safe side with worse case scenario my buddy came up with 11:5 compression any other calculations are welcomed. I also have some valvetrain noise and I believe its pushrods I used a thread from here that I found by searching and did everything exactly as explained and came up with 7.350 put them in and the noise pops up so I thought I might have messed up so I tore it down and replaced them with some 7.4's I had laying around the noise is still there any suggestions? This motor has 300 miles on it not even broken in yet.
