At this point I was planning on running as close to 15:1 as possible. I want to maintain as minimal a dome as possible while keeping maximum compression. Still waiting on my heads to come back before making any hard decisions. At any rate, I don't feel that there would be much to gain trying to increase compression beyond 15:1.

I was told years ago by a pretty sharp engine builder that at about 15.5 compression gains become vitually zero, and more compression just takes more fuel to bandaid problems. That is why my motor is at 15.1/1
