Do you know what application they fit?

As I recall, part numbers were stamped on the outer side of the flange that were visible when bolted to the head.

I do not. They look like they might fit a Chevelle, but the #8 pipe will hang below the frame right behind the front wheel if that's what it fits. I haven't test fit them in my Chevelle yet.

If they don't fit that, I'm thinking C2/C3 Corvette is most likely.

There were no stamps or anything anywhere. There's an ink stamp that looks like an inspector's mark, but no numbers that coincide with a part number.
