Which port do I connect the vacuum advance to?

Which port you connect the vacuum advance to will ultimately depend on your combination. I can tell you the factory used a basic rule of thumb to determine which port the hose was connected to. If a vehicle had a manual transmission, it was connected to a ported vacuum source.

It costs NOTHING in the form of power output to use ported vacuum advance.

How much vacuum advance can I connect to my vacuum canister?

Vacuum advance should be connected to full manifold vacuum; not ported. 8°-12° of vacuum advance is the typical limit (some canisters are adjustable). The (ported) timed spark port is only for emissions/EGR engines ( LINK ). May Gods grace bless you in the Lord Jesus Christ.
