Cylinder head question

If it's only TE exhaust side that looks like that I'd buff them off, install had seats and never look back.

I've fixed way worse. For a complete head rebuild with hard seats is $450.00 where I come from.

The intake seat looks horrible, and I'm not sure exactly how to describe the exhaust.:D
When I first glanced at the picture I thought it was a gopher hole in someone's yard.
