Is there an actual name for the manifold vacuum stem? My 2bbl intake manifold has that port plugged off, and I would like to get a stem for it. Is there a place that sells them new?

I have a new Holley 350cfm 7448 from Jegs. The only vacuum port on it is for the distributor vacuum advance (besides the PCV port) so it looks like I need a stem on the manifold to run my vacuum gauge off of. Is this correct?

vacuum tap (if it has one nipple), vacuum tree (if it has multiple). All you need is a brass fitting of the correct pipe thread on one end, and a hose nipple of the correct diameter on the other. Weatherhead, Dorman, NAPA, etc.
