another headers question

I have a set of Oldsmobile headers I cannot identify.
They appear to be ceramic coated and in decent shape.
The primaries measure at 1.75" and the collectors measure at 3.00".
The overall height is about 17" and from the top of the flange to the top tubes into the collectors measure at around 14".
These are for sale but I need to know what they fit before posting.
Thanks in advance, DLP

I don't think anybody will have a chance of identifying them without a picture.

They look like Hooker's to me. If they are, there should be a small plate welded on the tubes somewhere with their name on it.

Is there a part number stamped on the flange somewhere?

The slots in the flange and the pipe routing suggest Hedman 58158, however the Hedman collectors are somewhat longer. Also, Hedmans will have the P/N stamped on the flange. That number on the collector - 401 029 - doesn't correspond to any Oldsmobile headers that I can find. I suspect these are Chinesium knock-offs of Hedmans. This is what the Hedman 58158s look like.

I see a 401 029 on there. They can't be any worse than the instant rust, thin flange leaker Flowtech's.
