srp book says .018-.022 4 " bore with cast iron /moly/chrome rings or .005 per inch of bore 4.040x .005 = .0202. top ring. Ductile iron/moly/chrome is .005 per inch of bore .the second ring cast iron/moly is also .005/inch of bore.with the rings I run I run .019 top .022 second the bigger gap on the second ring helps relieve pressure inbetween the first and second ring so the top ring doesn't flutter which =loss of hp.
