    JE clearance sizing? how to find out

    How could I find out the clearance sizing of 81,5 JE-Pistons. I got them used and didn't get the needed clearance?

    Who can help?

    I have been advised from a few sources to run mine at .0035", also 81.5mm.

                0.09mm is 0.00354" so thats as good as the same thing... within +/- one hundredth of a thousandth of an inch anyway - about the size of gnats nob !
