SoDak Update
"SoDak was hydro locked when I tried to start it, so it seemed obvious that I was going to have to do something with the head gasket. Then I decided to check the head bolts for tightness. They were loose, but also felt crunchy when turning. After tweaking them, the leak stopped. So I decided to pull them out and clean up the threads in the block and properly tighten them. Well, this only worked for the first one. The second one came out all corroded and badly necked.I am still considering jumping into a valve job--I really should. But at this point, I think I will just put in new bolts, clean the threads, and see what happens. It is considerably more work to do a valve job, so I hope to avoid that for now. I will let you know how it goes"
