machine shop wants to know how extreme I want to go and he figured out by my body language that my son and I had different thoughts. Engine has 30 over forged pistons, mild cam upgrade, Edelbrock Performer intake with same 600cfm 4v. Heads are ok but want to "expand pistons" after honing block to keep clearance in range .005 or less. Either that or replace pistons to 40 over.. TALK ENGLISH TO ME.
He also said if I though it ran ok before losing pressure It should scream once together and running right.
