If in fact you are going to use your old pistons (after a careful examination of course), you might want to review some of the older engine-rebuilding texts on piston reconditioning. Checking piston ring grooves for wear (especially the top ring) and recutting where needed is one item (the standard ring would then use a shim). You might also consider either knurling the piston skirts or using piston expanders to try to compensate for the extra clearance; while this is certainly less satisfactory than reboring and fitting new pistons, it was a common-enough practice years back.
