The B on my stovebolt is ported. It doesn't matter which you use as long as the distributor curve matches. Some are meant for ported and some are meant for manifold. Ported vacuum only is in effect when your foot is not on the gas pedal. Once the throttle is opened slightly it becomes manifold vacuum.
