Since you have the ability to measure the cylinders, then mic the piston skirts to make sure none of them have collapsed. Also check the ring groove to see that they are still square. If not they can be squared up by you, and a ring spacer can be installed along with the new rings to bring the new oversized ring groove back into spec.
