Not really for a street engine. Im helping a local LS racer that competes in the drag radial class in NMCA and is making close to 1500 HP with heads that are not even ported very aggresively at only 300 CFM. Don't get sucked into the "how much does it flow" hype, its only part of the equation. But I would try to regain the area taken up by the width of the divider in each port. Forced induction is a great compensator and equalizer in making an engine that can't into one that can.LOL
