can you lower the compression ratio by installing thicker head gaskets? I'm wondering if i can install thicker head gaskets and run about 15psi instead of the 10psi i'm running now. thanks for any info.

I think you would need a 6.0L head that is 71 cc or something close. Your heads I think have smaller chambers.
