The impossible to solve overheating problem

I have news. A "bad" gasket is gullshit. "Bad gaskets" have been post fodder forever. All head gaskets on V engines have differences between left and right sides and "they work just fine." That is by design. I've no idea what the REAL answer was, here, but it wasn't "a bad gasket."
its not bullshit if the wrong gasket was used:
He took the heads off and found that whoever build the engine put a gasket on that was blocking a coolant passage, see pictures.
