Is heated air same as manifold vacuum?

So on my 66 dodge slant, running the super six setup with Carter BBD. I have 4 ports that I capped off. I also have a tube running directly off the intake manifold connected to the Air filter thermostatic dingus.

I want to just plug the manifold intake port (on the manifold) and connect the thermostatic dingus to one of these 4 ports on the carb. Any idea which ports I can use? I believe the lower 2 are heated air. Does that mean manifold vacuum? the other 2 is for egr thingy, and a purge thing, neither of which I have.
see pics.
