Do you know the Compression Distance on the Piston ? or the break point on the skirt ?(pin center DOWN to the tang end)
While 4032 alloys do run tighter than 2618 alloys, I would not really sweat the .0065 Clrc on a long skirt like a stock type piston, which sounds like you have ?
A little high yes, but for stock street type stuff generally speaking, 4032 cam & barrel stuff goes in around .0030" to .0035", with an additional .001" to .003" advised depending on rpm, compression, nitrous or boost(4032 are only good for very light N02 or boost anyways).
They might rattle a bit at .0065", but they'll run fine, 20W-50 maybe to quiet them down ?
