Is Thermo-quad Vacuum Advance Connection Ported or Unported?

[dibbons]

It seems my '72 small block distributor vacuum advance is out of service. As a side note, I would like to know if the designated Thermo-quad (6139S) front 5/32" connection is manifold vacuum or ported vacuum? Thank you.

Ported.

Some TQs only had manifold vacuum ports, so it's best to put your vacuum gauge on it.

I know that model, ported.
