They might be old Pontiac BBC Pro-Stock heads? I'll check it out.

Check this link.
The large port head might have been for Pro-stock type engines.
You have the small port version which was probably more for smaller sporstmen type engines 427-468
C.I. They are sort of obsolete I would think.

I'm also guessing the "582" is May '82 production date.
