I'd get new valve guides as well, and depending on the condition of the cylinder, you may need a piston and have it bored, as well. I actually found a guy on ebay that will do all the machine work for you on the head and the cylinder, as well as provide the
parts for a very good deal, just barely more than the
parts themselves through dennis kirk. Probably what I'm going to be doing in a couple of weeks.

If anybody out there has used this service before, I'd like to hear feedback as well!
