First, welcome to the club.
I believe you made a typo here...either that or are runing 6.10:1 gears.
Your block must not have any core shift. Anyone else running .060 over on the street would have serious overheating problems or broken a cylinder wall or two. I suggest you have the block sleeved to stock if you can locate some pistons and rings, or take it to 4.250, BB Chevy size. Pistons and rings are readily available in that size.
Plastigage will give you a ballpark figure of bearing clearance, but measuring the crank and rod or main bore with a bearing inserted will give you the true clearance. .003 is pretty standard for an FE.
