Are these heads junk?

I’m gonna go with “large port Commando” heads.

Edit: after looking at the pics again, looks like small guides and that they have the Magnum rocker stands.
Could be the aluminum Magnum Head.

Are the intake attaching bolt holes vertical like a magnum, or more like the LA style?
The Large Port head uses W5 intake gaskets and offset intake rockers IIRC.

Edit 2: looks like the Magnum style intake attachment.
