L28 compression - F54, P90a

Post by beeto » Sun May 20, 2018 3:09 pm

Hi all I have been doing a lot of research on the compression for my engine recondition.

I am running a F54, 86.5flat tops, with p90a solid lifter head.

I am aiming for about 9.5:1 compression. I see a lot of people do the 0.08 skin and shim, but want to avoid shimming. What can I achieve without having to use shims?
