any manifold vacuum will work, but you want it drawing from the plenum area, if not from the carb base (which draws from the plenum area). reason being, if you are picking it up from a single runner on the manifold, you are potentially drawing oil vapor into just that runner, instead of blending in the plenum. this could cause fouling, detonation, etc. it will work, but isn't really a good way to do it.
