Go for it. Dual-quads are my favorite. I doubt that you'll ever get into the secondaries of either carb, the primaries of each carb should fulfill the needs of the motor at WOT. I'd run the rear carb as the primary carb and set up a sliding rod arrangement to pull the primaries of the front cab in at about 75%, so that the throttle blades of both arrive at WOT at the same time.

There's nothing quite like the sound of 2-4's suckin' for all they're worth
