On my carbs it is the vacuum source the connects to the distributor for vacuum advance. I can send pictures if needed.

I got the last two bolts off and noticed that the inside of the intake is very rough. Would smoothing it out and polishing help performance or would it be a waste of time?

i have read that leaving the inside of the intake rough helps keep the fuel mixture mixed a little better. adds a little turbulence.
