Don't sweat it. That big blast of air from the air pump into the manifolds is just a cooling thing. It has no effect on your engine's vacuum. Just leave them open to the air, don't plug them. If you're worried about sucking dust into the engine, don't. The air just goes and right back out according to my mechanic.

Installed headers on 305 where do intake vacuum lines go now?

If you're talking about the air lines that force air into the exhaust manifolds from the air pump, that is an emissions thing. You could buy headers that have the threaded ports in them, add them yourself to headers that you've already bought, or defeat the emissions controls completely (not legal). Can't think of any vacuum lines involved with headers.

Where do the vacuum lines hook up to an Edelbrock Performer 2181 intake manifold?

On the sbf windsor manifolds, there is a threaded hole behind(toward rear of manifold) where the carb goes. You will need to screw in a vacuum tree there. As a basic rule of thumb, vacuum lines will always attach to one of the manifold runners that lead to the intake valve(s). Also...pretty much all carbs have vacuum ports. The ones in the base plate are full vacuum, while the ones in the body are usually ported or timed vacuum( like for dist advance).
