66 barracuda 4 barrel manifold

Looking for a 4 barrel manifold for my 66 Barracuda. I think what I need is a commando manifold. From what I can tell it is only about 3" high. I am not positive about that because the manifold and carb are still on the engine so it is hard to be exact. If I go any higher than the original then my air cleaner will hit the ribs in the hood. Also any other suggestions would be appreciated.
