Without performing some tests of which your buddy should have done PRIOR to taking the engine apart, I really can't tell you what the problem could be.

AnswerThe FIRST thing I would have done would have been to pressurize the coolant system and see if any bubbles could be seen in the radiator when the radiator cap was off and or the pressure gage started to drop in pressure. That would have given me an idea as to possible head gasket, cracked block or cracked head or heads BEFORE I tore the engine down.
Did your buddy put the GM TABLETS in the coolant system as this is a MUST do item.
Ask any parts place for these GM Cadillac tablets (pellets).
