I have a 77 with the same problem. One of the the three studs does not
dead-end into the head material but goes into the coolant chamber. Over
the years, use/corrosion has enlarged the thread clearances in the head
material so the stud is no longer as tight as it should be. I use lots of
teflon tape to retard the leakage, this may work for you if it is the same
problem.
