Help me identify these vacuum lines!

Hopefully the pics show what you need. I did some work recently including adding manual choke which forced me to go to an aftermarket air cleaner. Now I am wondering what these vacuum lines do. My smog pump is disabled. I am guessing they are unnecessary at this point and would like to get rid of them to clean things up.

Here's the pics- they should be self explanatory:

You can see the two lines broken off. These connect to the passenger side base of the carb and are currently blocked off.

Any input is appreciated!

The two that broke look like that black molded rubber that goes on the temperature actuated vacuum switch (yellow piece on the intake manifold).

The one that goes to the top of the air cleaner I believe leads to manifold vacuum. The (old) aircleaner should have a bi-metal switch on it that goes from manifold to bi-metal switch to diverter valve on the end of the air intake housing to divert warm air from the exhaust manifold into the air intake. There should have been a hose from the end of the air intake housing going down to the passenger side exhaust manifold shield duct where the hot air is pulled from.
