HI, Egge Machine has piston rings listed for the Ford 223 six'es from Standard to .080 over.

But please note that you must take carful measurements of your piston ring groves width and depth to be sure they will even work for your Pistons. If they don't have what you need then you will likely have to have a custom set of rings made to fit from an aftermarket ring company. Good luck in the hunt
