Professional Products Crosswind Intake Manifold

I have a vacuum leak somewhere. I've sprayed around the usual suspected areas and haven't found the leak. I've had great luck in the past using a cigar to find vacuum leaks.

Problem is the new manifold doesn't seem to have a vacuum port. All of the plugs (in the manifold) I've pulled all lead to the water jackets. Seems like the only ports I have are in the carb. I haven't tried blowing smoke through a carb port yet but I'm about to try.

Anyway, wondering if anyone has this intake manifold and whether or not they have a vacuum port? Maybe I'm just missing it?
