I see what you are getting at it makes sense to me now. Ok so I been doing alot of research and I have a question. I gotta go look at me heads and see how much area there is there on the quench pad on the chamber but I'm pretty sure after he miiled them they are pretty much flat but I got to check. I was looking at the kb190 pistons they have a .050 dome with the same ch. So the piston will be .012 under still but the dome will be .038 above the deck with the thick gasket that will give me .012 plus how much (if any) is in the head obvious if the pad is even with the head surface what wont work but it it's anywhere around .025 that would work out perfectly. And give me a cr of 10.8 so here is my question. I'm now creeping up into the mid to high 10s can I still run pump gas in the high 10s or low 11 range?
