Carter AFB inlets/outlets and uses??

I picked up a Carter AFB Competition Series 9636SA four barrel carburetor with an electronic choke built in 2001. I bought a rebuild kit from Mike’s Carburetor Parts and cleaned/rebuilt the carb. I’ll put it on a fresh 318 I’m almost done building, which has vacuum advance, power brakes, and std PCV valve.

Which carburetor inlets and outlets (1,2,3,4,5,6 in photos) do I need and which ones can I cap off?

Can some of you smarter more experienced guys do me a favor and tell me which of the fittings in the photos “should” connector to what? And why one port is better than another for certain uses?
