There isn't much extra flow available removing the pushrod pinch, but there is power available by doing this!
You help reduce the smallest area in the entire intake tract, and thereby you help keep inertia up during the intake cycle.

It helps topend HP and HP past HP peak, but I've also seen it add TQ below and above TQ peak!
For a true 7200rpm, I would use the Indybrock's hands down.
