do it the right way, follow clymers, remove the topend, check the rings, clean the pistons up, put everything in a cleaning solution, then rebuild the whole thing, get your crank checked out too...have it trued and welded, maybe send your flywheel out to lightened,do a shift star mod......
youll have peace of mind for a long time that your engine is in order...youll just loose a lil money for new seals and gaskets and some time, but doing it the right way always pays off., youll have a new motor almost!!!
