From my prospective, I think the average "close mount" dual carb manifold setup is more for looks, as compared to actual performance. A single four barrel would work better.
I have a Offy Super wide mount manifold on my 59AB with a pair of 97's, of course this application requires a side mount generator.
The front choke is wired open, the rear carb choke is attached to a modified choke cable.
Fuel is delivered via a fuel block on the firewall supplied with fuel from an original type of fuel pump backed up with an electric pump near the tank that is switched separately.
The air cleaners are stock type oil bath that have been modified to hold disposable paper filters.
The whole setup might not be to pretty, but it is functionable.. I drove the car to work everyday for years through summer heat and winter blizzards.
