You cannot base rebore sizes on a digital calliper measurement. You need a decent Mercer type bore gauge. Taper & ovality needs to be assessed to know the minimum size that it'll clean up to.
Find your machinist (by recommendation ideally) and take them your block. Get them to measure and assess it and then buy the pistons. Bear in mind that some pistons (such as Tony Betts') are sized in metric which can be a useful size between standard 10 thou steps.
