100% agreed. however my piston heights aren't all exactly the same, they vary by .006".
.020 is the deepest hole.
My quench will actually range from .038 to .046.
The shallowest piston is .014, otherwise I would have used a .015" steel gasket, I just wasn't comfortable with .029 clearance on a couple cyls, so I compromised with a .026 head gasket.
Is .006 a lot? I don't know and it really doesn't matter at this point, The motor is going back in. I need my truck.
No matter what, too much clearance is better than not enough.
Piston----><----Head
