You knew I'd have to chime in here too

".....I have to agree with Eric on the sensible level. One good carb will outperform and be more suited to an engine that two or three carbs......"

Nor could I agree more...........That being said what fun is just one carb or FI

I can't speak from first hand knowlege on the BG 6 shooter but I've run both Tri-Power and Dual Quads on an engine or two . Running a big cam and getting a clean idle can be a bit of a challenge anyway and a real pain on a tri-power set up.

While I tend to go for the Tri-power setups, I think that in the long run you might be happier and get closer to what you want running a dual quad setup.

With the stroker and big cam, I'd suggest that you go with an Edelbrock intake, progressive linkage and 600 CFM carbs. I think you will find that they are a bit more responsive than the 500s would be and a bit more forgiving on getting a good idle. The secondaries are controlled by an air valve so they will only provide the amount of air/fuel that the engine can take. (Experience from running dual quads on a 383 stroker in a 58 Chevy prior to going to Tri-power)
