Just get the howell automotive rebuild kit and be done. Strauss is right on two accounts. All you need are pistons/rings/rods, but I would pass on the total seal rings. They are actually detrimental to the lifespan of your engine. Also, if you do the internals, do something with the fuel as well. Easiest thing to do is 440/S-AFC route. Throw in a MSD DIS-2 for help with your timing and spark, then tune for 15psi pump gas daily driven.
