I do not think you can see anything port wise with the gasket in place. As far as magnum goes the valve covers should be 8 bolt as far as I know.



10 bolt valve covers and the heads with air injection have an extra boss below the exhaust port that is noticeable, it is not there on the OP's heads.

Here's a pic of me cleaning out that air injection port on a 79 360





I realize that but I believe his picture has the gasket covering them up.
