You *are* replacing the head bolts, aren't you?
Next time you've got the head off, run a straight edge over the head and block, I'm willing to bet you'll find one or both of these is warped. This seems to be fairly common on particularly the earlier 3.9 motors. The other thing is casting sand left in the block; this will fill up the radiator cores over time causing it to overheat.
Seems to me that Ford were in such a rush to beat the Commo out, they screwed up a fair number of things with the early EAs
