This exactly. Which is oddly enough why I posted the Street Dominator in case if it’s a 3.58 stroke engine.
Just because of this, I would be inclined to try it first if I went with a single plane.
Since we are talking about a heavy vehicle, a performer air gap with a one inch spacer (a super sucker or a shear plate between that and the carburetor probably wouldn’t hurt anything either!) and the plenum divider milled one inch from the floor would probably have an advantage here. An air gap intake flows within 7cfm port to port, so fuel distribution shouldn’t be as much of a problem as speculated. The blow through design with a turbo makes for free after cooling. It makes sense to me to use an air gap to maximize that effect.
