The reason I ask is this: I got Cippola'd on a "never fired standard bore short block" from another board member (who shall remain nameless at this point). It had used stock pistons in it. I disassembled it and the bores mic'd out w/ .006" -.007" (taper in the bores) skirt clearance. Any chance that aftermarket pistons will fill the holes any better. Either way I've got to buy pistons but it might save me a bore job (I've already gotten that from this a**hole that ripped me off!! LOL)
