Check on the side of the head near the passenger side firewall, where the water pipe connects. Pesky and inaccessible, the paper gasket often gets folded or dislodged causing a leak there.

Well, this is fun.
It would appear that I have now stripped one of the threads in the head at the pipe.

Do you think I will have any luck with some kind of thread repair kit? Helicoil?

As you know, the location of those bolts is not easily accessed. I dread pulling this head off again.

If anyone has some kind of magic self tapping bolt suggestion, I would be elated.

ok so in case anyone needs this trick...
take the bolt and hold it with a pair of vise grips on the head.
take a sledge hammer and smash the threads flatten them a bit on both sides so then you have an "oval" type bolt.
then this new bolt will cut new threads use the proper torque and walaa....
