    James – as Dale noted, I would replace the rings on both pistons. And since you’ve got it all opened up anyway, I would run a Flex-Hone won the cylinders to do a good job of deglazing the cylinders and getting a good cross-hatch pattern. Clean the block real good after honing and then oil the cylinders to prevent flash rust.
