I imagine thats true, but with holes in the gasket with no place for the water to go in the head, wouldn't that continue to wear the head? And there is corrosion there, so it actually is an area that is lower than the head surface. So the gasket may not seal and you have water trying to push through on top of that. Doesn't sound like a good mix. Should the correct gasket have holes in those areas? seems like it should be closed off.
