Thicker headgasket, but it's fine to boost on 9.9:1 if you have it tuned properly. I run slightly over 10:1.

o thats cool...but im going to build the bottom end but now i dont know what pistons to get...for example if i get srp 9.0:1 pistons for a y7 would the compression still be the same after i put the y8 head...like is it only the head gasket that bumps up the compression on the mini me swap?
