Nope. But I know right where to look now. You do to. Just look at those pics I linked to in the topic. With an inspection mirror and a flashlight, you should be able to see most of those cracks. OEM exhaust manifold gaskets would have prevented perhaps SOME of them.
with that second video you proved yourself wrong, when you rev the engine the coolant doesnt pressureize, it justy moves faster.. if it was a head gasket, when you rev it wouldnt change that much because it would effectively be within the same general pressure, but would blow more from the exhaust leaks by pressurizing the exhaust more
