A block test would be my next stop,
It's a reactive liquid in the tester and goes into the expansion tank.
The liquid is blue but changes colour in reaction to ANY combustion gas in the coolant.
Your description of "FRIED" top gasket which I'm assuming you mean the head gasket makes me wonder if the head was machined skimmed flat when the head was off?
Which is what I would have done to any engine that was fried!!
