I would check your timing with the hose off and plugged, then hook up the vacuum advance and adjust your carburetor mixture screw(s) for proper mixture, and then the idle speed adjustment for rpms.
Ported vaccuum is a result of smog regulations and unless your vehicle has to undergo emmissions testing full manifold vaccuum is the way to go.
May I suggest reading this article on distributor tuning
http://www.hotrodders.com/forum/distributor-tuning-theory-part-1-a-59033.html I don't know how many here remember the California mandated NOX modifications ('70s?) for all cars '62 and newer. Basically it was a kit that consisted of a plug and a sticker, the vacuum advance was disconnected and plugged, the timing retarded, and a 'Certification' sticker was applied. The engines ran like crap and overheated, but the Air Resources Board could pat themselves on the back because now the older cars ran just as bad as the new ones with retarded cams and ported vacuum. The good part was after the inspection you could just hook the hose back up and reset the timing.
As always, just my opinion, but it works for me.
