One of the air cleaner bases with the really big radius will help direct air flow. I don't know that the K&N lid helps that much. It may or may not, depending on the area around the carburetor, and only experimenting will tell you.

You need an inch or so at least between the hood and the vent tube. The Q-Jet is a very sophisticated fuel metering device, and air flow around the bowl vents and the feeds/bleeds is critical, excessive turbulence or a lack of clearance around them can upset the circuits.

The Doug Roe book on Q-Jets is one of the best sources for Q-Jet information and tips. No Q-Jet racer should be without a copy of his own.
