do you recommend i take the vacuum reading from the ported side (spout up near the top on the passengers side) or the manifold side (bottom of the carb on the passengers side near the spacer)? last time i took the reading from the manifold side

Low port.

Manifold vacuum is the low pressure under the throttle.

The high port is the spark port. Goes to the distributor.
At idle that should be at atmospheric pressure (no vacuum or close to no vacuum)
