I have a 1� open spacer under the Holley 750 (4150). Would I be better off with a 4 hole, 2 hole or combo of both �� each? Thanks, Mike

An open spacer above a dual plane with a divider in my mind doesnt make sense. But maybe I'm wrong? Just seems the 2 or 4 hole would be better at directing the air straight down into the plenum...
