Hey guys! I am building a B20VTEC with a GSR head. I recently picked up some JDM Type R pistons (P73-00) for the build. I want to run 91 pump gas, but I am super scared that my compression is going to be way too high, and my piston to valve clearance is going to be way too tight. Does anyone have any info on this that can put my mind at ease? Thank you!
