Holley 1920 R-4003B, 4162

Here is the passenger side for reference. The port to the left, I assume would run to the distributor (which is the exposed line with clamp to the far left). The port to the right with the brass fitting is the anti ice, which I know to run to my air cleaner. This would leave my vacuum amplifier, charcoal canister (if the opposing port is not the correct placement), and pcv valve unaccounted for. Any advice? My manual is exclusively partial to the 1945.
