7.4 Exhaust Manifolds help please

[Gerkin]

Hi all.
Having to squeeze a pair of 454s into an engine bay. The manifolds on them were PCM cast irons and they were totally shot when removed. They since do not make those manifolds anymore.
I am looking for 2 sets of narrow manifolds that fit BBCs. Does anyone know of a company that makes something like this?
Attached is a pic of them before they were pulled. Pretty tight fit.
Thank you for any help you can provide.

BARR made the castings for PCM (And Volvo, etc). get a set of BARR manifolds.

Thank you very much. I think the Barr manifolds are approx 1" wider than the PCMs. I don't think I have 2"s of room
