When my '84 7 passenger was given to me in '91, the head studs had
corroded badly and at least two had stretched.  I could actually wiggle
one of the capnuts and, of course, it leaked.  The PO had overheated
that engine and destroyed it but I tore it down for analysis after I
replaced it.

Stretched studs are a possibility as is a crack in the head at that
point.  You won't know for sure until you disassemble, unfortunately.
