no. One is manifold vacuum and the higher one is ported vacuum which only receives a vacuum signal when the throttle plate is open.

The hose for your heater controls should go to your vacuum reserve canister. The other hose from the canister can go to the non ported (the lower) port on the carb if you have no vacuum taps on the intake.
