The one on the passenger side is ported vacuum for your distributor.
It drawn from just under the primary throttle plate
The drivers side is straight manifold vacuum and is drawn from under
that carb
Another thing... use the front port for your PCV ( if necessary) Using
the rear port only loads up with engine vapors and condenses oil in the
hose until you use enough pedal to open the rear barrels. If not used
enough, it could dump enough oil into your rear cylinders to foul a plug
or two..
