SCE Head Gaskets

If that is a gasket with the wire built in I'd pass unless you cut a groove in the block Felpro makes something similar but it's not in copper.

Unless you really need a copper gasket, I'd use something else. They are a PITA to seal water and oil.

To b done correctly, a copper gasket should have a stainless steel wire in the head and a receiver groove in the block. And you still have to get oil and water sealed up.
