You, know, I was told that same crap when I fixed a BHG on my Toyota P/U with the 22R. The truck had 250K on it. When I pulled the head, I could still see hatch marks, so I know the bottom end was good. The machine shop didn't want to do a valve job, because they said I'd wreck the bottom end with re-freshed compression. I told them to do it anyways, and was able the hang around while they did it. Put it back together, and it drove great. The engine was still running great at 325K when I sold it.
