There's an episode of the show Engine Masters where they compare carb and TB injection on an LS. They started with a dual plane but couldn't get the injection to work with it due to air signal or something. They had to swap to a single plane and it worked fine. Not sure if it was only because it's an LS or what
That said, I ran TB injection with an air gap on my SBC for a few years without much of an issue. I think you'd be fine and like the longer runners for street driving but I'd keep an eye out for anything goofy going on
