Can I use B or C body manifolds fore better flow on my sleeper GTS?

We could get sneaky and plumb a fogger into the bottom side of the intake but this isn't that serious of an effort. Most of what I have in this car aside from the body itself is left over from my red '66 charger. I have pondered whether a fogger would help or hurt over the plate. I would think a lot of that has to do with how balanced the intake manifold distribution is.
