My 440 Build. Which intake and WHY ?

Look at your numbers and you can answer the question.

The "regular" intake is better below 3000 RPM.
Exactly, and every part of my build makes power in the "under under 5,500 range" but yet I have local car friends, pro's and forum friends mostly telling me to get the RPM... but none give a reason. Figured I'd lay it all down here and see what folks think. I'm hoping to get some reasoning rather than just "RPM".
