Hey guys, I have a 51 8ba with a 4” crank, bored .060 over, and 8rt heads. I bought the heads at the same time but don’t know the history of them. I have 130-140 lbs of pressure in cylinders 1-4 and 110-120 lbs in cylinders 5-7. I did the tin foil balls thing in the cylinders on the 5-8 side and it seems to have .025 piston clearance with the head tightened down with no gasket. I’m thinking if I mill .020 off the head and use a copper gasket I should be around the .050 you guys talk about. Do you think that will get the right side to match the left side.
