Piston Ring Port Sizing

Has anyone come across any standard for the maximum port size (along the circumference of the ring) that cast iron piston rings can slide over without danger of scuffing the ring and/or port, based on ring OD and thickness?

Re: 1-1/2" Scale NKP Berkshire Parts- Part 1

Well like I said in the writeup, one driver casting is missing but I anticipate being able to provide it later, at the current retail price of course.
