I have a set of standarad pm7 pistons the shop doing the work said that I will need to go .030 or .040 over. I am going to get the .040 they said it was the max I could do before resleaving. The car is na running delta 272 cam and full valvetrain. It is convereted to obd1 using hondata s300. Just wanted to check into this further the shop said it would be fine
