Your machinist, more than likely stopped at .020 because he will want to custom fit each piston to each cylinder hole. This is a must do for forged slugs. My machinist will be super careful and do it with Hyper slugs as well.

And like he said. You need the pistons to finish the bore job. You may end up at 0.30 over.
