The two ports on the intake manifold, tapped 1/8 IP, are for a primer system using a hand pump on the dash. You don't see a lot of them, but that's why the fittings are there. Doesn't mean you can't re-purpose one for vacuum, though. The PCV inlet would be another possibility. Or just drill and tap wherever.
