dual quad low profile?

I have a natural aversion to carbs that you have to take the top off of to tune. :thumblef:
The problem with the AVS (good carb!) is that it's a slight spreadbore......the manifold isn't. AFB's are manual secondaties, right? I can't see stuffing 1600 cfm down a 340 at lower rpms when I stand on it...like trying to drink two beers at the same time :drinkers:
Actually the six pack looks like the hot setup for this motor, but the cost............. :wack:
