The head gasket is an easy test - buy an exhaust leak detector kit on Amazon or harbor freight. Fill the test tube up with blue dye, stick the tube on to the coolant fill port, rev the engine, and pump the ball on the test tube. This sucks gases out of the coolant tank and if there are combustion gases present it turns yellow.

FWIW I just went though a similar process. Coolant spewing EVERYWHERE from overflow tube with every drive. The burp valve was bad and needed replaced. Also, I'm convinced that I somehow overfilled the coolant system. As you pressurize the system it forces the coolant level down, and if its overfilled then there's no where for it to go but out.

You are correct though, the system should hold 1.4 bar pressure without problem. At that point the bleed valve should start to rise like a turkey timer. Around 1.8bar it will actually start to bleed of excess pressure.
