If the threads in the head look bad, buy a thread chaser. Available at most automotive shops. Not very expensive and may help save the head.

Blew the spark plug right out of the head.

Did you check to see if the proper spark plug was installed? It could be the wrong reach (thread length).
Threads are ok. Slight damage not too bad. Correct plug. I was able to put it back in and torque it down with no issues. I will pull the shrouds later today and check the head bolts and valve clearance before I start it again. Really concerned about overheating. Don't want to have to rebuild this engine. I agree with the possibility of high compression. I understand these engines have compression relief making it hard to check. Not sure how to go about identifying/resolving a high compression issue. I've ordered a head gasket and will pull the head when it arrives. Hopefully answer a few questions upon inspection.

Don't forget to decarbonize the head. These engines also have counter balance gears which have been know to give trouble. People usually remove the gears. If you are worried about overheating, use a good quality synthetic motor oil. Amsoil makes a straight grade 30w synthetic oil.
Thanks guys. Just received my manual on CD today. I'll look into the counterbalance gears. Valve lash and point clearance were both a little wide so reset them and head gasket will be in this week. Had to order the little grommet for the points cover as mine was disintegrating but there at least. Was kind of surprised to find them. Figured I'd be making my own.
