Got a quick question. Would the headgasket seal this coolant passage?

Copper RTV is able to withstand exhaust temperatures and is typically used on exhaust components. This is well beyond the temperature range of a coolant jacket on the deck.

Personally I'd give that little spot a skim coat of epoxy just to be safe. Fill the eroded spot, drag a razor across it to ensure it's smooth, and if you're really paranoid a dab of copper RTV when you're done. As is it should seal, but it doesn't hurt stacking the deck. Just have to make sure the surface is flush if you're using epoxy.

I figure the headgasket should seal all flat surfaces on the block and head itself, except for the openings on the gasket. Unlike the intake manifold gasket where there is rubber around the runners and coolant passages. Am I right?
