Yep. Vacuum leak. The top plate of the intake plenum in the cross-fire is another likely spot. There's a bunch of bolts there, and the gasket surface around the plenum is skinny, so it's easy to get a leak in that area.
A good way to find a vacuum leak is to spray some engine starting fluid on suspect spots. If there's a leak, the engine will speed up!
