Vacuum Connections (292 w/ Holley 4 bbl)

[mattdmeyer]

I'm getting my project back together, but I had a few questions on the vacuum connections. I upgraded the stock manifold and monojet carb to an Offy with a Holley 4 bbl carb.

So far, we have the following connected:
The fuel line from the fuel pump to the fuel inlet on the carb.
The vacuum line from the HEI to the little port sticking out the side of the carb. I'll have to get a picture of it tomorrow to better illustrate this.
PVC valve going from the top of the value cover to the intake manifold.
Power brake vacuum line from the power brake booster to the manifold.

The one I'm scratching my head on is the second line on the top of the valve cover. That used to go back into the air filter box when using the 1 bbl rochester. But now that I'm using the Holley can I just plug that up?

Am I missing any other vacuum connection?

Thanks!!
