Nah I used to get 30,000 give or take on a top end then bore it new pistons and rings and good for anther 30,000. Do that 3 or 4 times then have to rebuild. As long as the top end was done before anything broke.I left out valve guides and grind valves back in (lapping in most cases sometimes recut).
