I should have said in the OP, but the leak is above the freeze plug. It's hard to tell in the pic, but it is definitely leaking from the passenger side rear corner of the head. I talked to 3 different shops, and they all said it is rare for just the head gasket to corrode. Most likely a warped head which means the fix will cost almost as much as the car is worth. We'll probably try to sell it as is and move on.
