NEVER EVER use manifold vacuum for vacuum advance on a car that has a centrifugal advance distributor and single port vacuum advance unit, EVER, unless you like having over 30 degrees of advance at idle, so your engine may idle like crap at idle.

Also, ported vacuum has absolutely ZERO to do with emissions.
