I can understand your perspective, but I don't agree with it. On Honda's they use a hardened steel sleeve in the block and they use hardened steel valve seats in the heads. From my experience their design combination is pretty impressive.
I have an 89 that is at 220,000 miles. I put new, stock size rings, rod and main bearings and had the head reworked, because I had it apart. The rebuilt engine doesn't use any oil and runs great. I have never had a steel engine get even close to that. Some people say they have, but I sure haven't.
