Ouch those valves are in great shape...lol. Time for new seats....a good machine shop should be a help. Give them the head and valves and also ask about valve guides....I replaced mine also.....I also was able to reuse my main bearings after plasti-gaging them, so was lucky. I think my guides came from some mini van a dodge caravan I think that my machinist made fit.....but could be wrong or that was another engine ......but this sounds right..?
The only things I didn't replace was the block, crank ,head, crank bearings, rods, cam. If I remember correctly.. Everything else was replaced with new. All from MW-SMART. Oh...the vacuum pump for the brakes on the righthand end of the engine I got from Romania, also excellent, just searched it and found it there as MW-SMART didn't have a new one.
