Hot Rods Need info on SBC ceramic coated headers.

I have a set of SBC chrome looking ceramic coated headers.
Never been used.
Block hugger type,
4 bolt collector.
At least 10 or 15 years old.
I am hunting for a 90 degree bolt on collector but everything I see is a 3 bolt collector.
Does anyone know who the manufacturer of these might be?
Should be a short list for ceramic coated SBC block hugger headers with a 4 bolt collector.
I hope......
Anyone??????

 

Header companies come and go over the years, Make your own flange, or have it made

 

Google search 4 bolt exhaust flange. You need to measure the bolt hole centers on your header flange so you get the right size. Also help to measure inside diameter of the header flange.
Good luck with your search.

Street&Performance sold headers with a 4 bolt flange.
I think they closed down.

 

Easy enough to fabricate with 1/4" flat stock and a 90 degree bend.
