do not forget to update this soon. also....you compression ratio being at 9:5:1 perplexes me
it may because of the thinner deck on the heads. but with my 68cc and ls9 gaskets 3 major companies, aes, slowhawk performance, and texas speed all have me @ 9:3:1.
Either way, I will just have them milled later on next year when time comes for the re tune. Looking forward to updates.
