A couple things come to mind, in no particular order.
Does it have a water pump or is it thermosyphon cooling?
If it is thermosyphon, was the radiator full? Did he pre-mix the water and antifreeze?
Did anybody flush out the block's water passeges? There are some very small openings that can get blocked very easily with rust and/or scale.
Did anybody flush the radiator? It could be full of rust and/or scale.
It is possible that the head is warped, but it wouldn't be high on my list of suspects. Did anybody put a machinists straight edge on it while it was off?
Did you know that the later service manuals call for 80 ft/lbs on the head bolts? I understand it is because modern gaskets need more torque.
Did he use sealer on the head gasket like most gasket makers call for?

Just a few thoughts
