Help identify mystery headers
 

I ended up with a set of headers that I can't figure out what they are for. Can any one tell me what these headers may fit?

That's the "Stahl" pattern, Jere created it decades ago to allow easy installation of large tube headers on a small block head. Originally, there were adapter plates, with counter sun holes, and later, some cylinder head companies machined that pattern into the heads.

Whatever they are off of, those aren't the original flanges.

Thanks Looking at the tubes and comparing them to ones online I thought they looked like some E body mopar. But the flange didn't match this would make some sense.

I bought them assuming from just pictures that they were a stall small block chevy. But after setting them next to a pair of small block header it became clear they were not for a small block Chevy. I do have an old set of stahl headers but a much smaller tube than i need now.

That would explain the fact I can not find anything at all on the flange or the tubes.

Do they match the center line spacing of your exhaust ports? Do they match the gaskets for your other Stahl headers for the bolt pattern?

No they are not the same

Schoenfeld headers has a nice chart on their website showing header flanges
