On a Windsor? Not needed if it is a S&S mostly street motor.

.0015-.002 on the rods, .002-.0025 on the mains... piston tolerance is recommended by the manufacturer. 10.5:1 c/r will be tough to do without domes. With 58cc chambers and assuming flat tops, you'd need the pistons .005 out of the hole, .030 head gaskets netting you an assembled quench height of .025
That's too tight IMO, at least for anything above 5500-6000 rpm. You don't want your heads getting to know your pistons like that I squeezed 10.06:1 out of my 333 with a quench height of .035, and even with forged h-beam rods that's boderline for stratosphere rpm use

If I remember correctly, I had .006 crank thrust and .014 rod side clearance (2 rods, one journal)
