different kinds of rings

I'd do a LD on it before teardown, and let that be my guide.
The first three winters after my engine was built, I took it out for inspection. Each time it went back together with the same rings and cylinder finish. It now has over 100,000 miles and still no smoke. I have not Leak-tested it now for many years, but she still performs pretty good.File-fit plasma-moly tops, cast 2nds. And yes, I chemically removed the carbon ridge before pulling the pistons out.
