Im starting to put my motor together and heres my question. Since the bore of a standard 302 is 4 inches, I measured with a bore gauge and my cylinders measured 4 inches and .002-.004 thousandths. Is that extra .002-.004 thousandths too much wear for a standard size piston? I really dont want to bore it out if i dont have to. Thanks
