anybody running the offenhauser / 6 dual carb intake

More trouble than it's worth? IDK - better fuel distribution, but can you use more carburetion? I don't know the answer.
It's a little bit of work to get it going (besides the 'I need to get around to fabbing fuel lines' part) - you have to modify the throttle linkage.

In the meantime, here are some pics from other people's cars (I think some of those have been modded to take 2 bbl carbs):
