I'm gathering from all the posts that I should use either Iron or Moly, but not sure exactly which. I may decide to just leave the rings alone as good as the cylinders are (no ridge, no smoke, plugs are light brown in color, compression was 165-175psi across the board)

Thanks for the info!
If you are replacing the pistons, then do not consider reusing the rings. If you are going 'glaze bust' the cylinder, then do not consider reusing the rings and I would say to use iron rings if you are not reboring - IMO.
