UGH all this plastigauge talk make me :jawdrop:

The tolerances in a performance engine should NOT be measured with plastigauge. Inside and outside micrometers are your friend. If you don’t have these tools you shouldn’t be doing performance builds or rebuilds. Plastigauge is best left to rebuilding 150hp Chevy truck engines
