RNMM makes a good point, there. Perhaps look into resurfacing, though if there was no problem with head gasket leaks, it might be more than necessary. I've heard the resurfacing isn't expensive, but can also be done on the shop bench, using a sheet of sturdy glass and some sand paper.

When you get the valves off you can check to see if any of the valve guides have slipped down...I had two do that, and did have to send the head to a shop. Guy did a great repair.

And remember: no garage or shop should be without fresh, delicious donuts. Donuts: they're what's for dinner.
