Dual carb manifold proper/alternative carbs

Can anyone tell me what carbs were used on the dual carb manifolds? Has anyone adapted anything and if so what results? Suggestions?

Am also considering 4 SU's..any advice pro or con on that or what might be a good 4 carb set up where I don't have a whole lot of overhead space (low hood line)?

Thanks for any help.

Carter or Stromberg

Just jets and spacing are different between series. The rear one has a 1" damper under it for cold starts. Any carb will sit high. The stock air cleaner adds only another 2". Don
 
Carter for 41-42

The reference list is missing the Carter carbs for 41 - 42. Both years are from Buick shop manuals.
