super six now where the heck do all these vacuum ports go to?

Myself, I just blocked off everything on the bottom of the air cleaner, so it would function as a pre-smog air cleaner with snorkel. I also took the flap out. Yes, the float chamber vent needs to be left open. I only hooked up vacuum advance, PCV, and the choke pull-off. There was a small vent tube on the rear (firewall direction) that also stayed uncapped, but I may not have the same carb you do.
