you know, i hate to say this, but if you are going to replace the rings, i would HONE IT. get yourself a hone with FINE stones on it, and some kerosene. hook up your variable speed drill and go to work. if your unsure how to achieve the CROSS-HATCH as hotrod mentioned, goto your library and check out a book on engine rebuilding . honing is very simple, and should be done if you are replacing rings. it might not be a bad idea to check the trueness of your cylinders, using an inside bore guage and a micrometer, check the top , bottom for taper, and for trueness. chances are if your cylendars are out of round, rings will be of no use to you cause they just will wear out again. but if everything looks good, giver her a light hone, and throw her back togather. and YES take it easy for awhile so that the rings will SEAT properly.
