Usually I would think that a .0035 margin as insignificant since it is such a small number. Is that good, bad, or ugly?

I asked him if .060 will be the final bore, if it is, I don't see it as a significant issue, I have a triple pass aluminum radiator, high-flow aluminum water pump, and I assume aluminum heads will help out a tad too.
IMO you're OK w/those numbers, given the circumstances. As long as the "-" is the piston down the hole, not out the top, and that both banks match, and that each corner is the same- all within reason of course.
