I am going to be doing a Y8 head swap on my 97 civic that has a Y7 setup in it. I read just by doing a Y8 head swap on a Y7 block will give you 4 points, a 9.96:1 compression. I am replacing he pistons and rods while I am in there. The problem is, I need to find a piston around 9.5:1. I dont want to run a 10.5:1. I am trying to keep it right around 10.1:1. It sounds like i am going to have to have custom pistons made but figure i would post if anyone knew of any 9.5:1 pistons so i can achieve a 9.9-10.2 compression. I am keeping the motor NA
