Dual 2 bbl or 4 bbl carb intake

I have a two one barrel manifold (Offenhauser) that I am modifying to be twin two barrels. They will be in line like on a V8 tunnel ram and will open at the same time. The way the manifold is made, I think this will have to be the way it goes. Linkage shouldn't be much of a problem either with this setup. As others have mentioned, a single 4 bbl will be easier to tune and will probably make more power but I like multiple carb setups for the cool factor (I have a tunnel ram 2-4bbl 440 that runs awesome).
