I'm going to restore (try to) a set of Italian Weber 40idf carburetors to put on a 1.7 engine. I have two sets of manifolds... one set has a vacuum port on one runner (each side of engine), and the other has none at all. Is one type favored?

Which do I want to use, and why? - I have no idea what the vac ports would connect to. If they help even out idle, I'd want them I guess. Thoughts?
