Out of curiosity, does the oil galley plug hole dead end square into the head bolt?
If so, how does so much oil pump through the galley hole? Is the head bolt hole itself an oil passage and oil flows around the head bolt shaft?? Or is there some other intersecting oil passage before the head bolt that the galley hole is part of?
