Help with Head Gasket selection

Looks like heads have been cut for O Rings.
I believe PittsburghRacer ran into a similar situation as you have.
IIRC he installed SS wire and filed them down, even with the surface.

They aren’t cut. It’s an impression. Like the gasket had a ring like those SCE gaskets do maybe.
