Performer RPM Intake: Improvement possible?

Hi Guys,
i´m running successfully an EDE Performer RPM Intake on my 408 SB. At the moment i´m switching to some cnc ported heads and a bigger cam (hydr. Roller, 248°@.050" / .620" Lift, 113° LSA) and since the intake is removed from the engine i thought about improvements. I use a 1" tapered spacer and like to keep it, it improved idle noticeably with the old cam. The divider in the intake looks like it´s not helping airflow - what do you think, is there anything to make it better? Of course, i could buy a single plane....but for now i´d like to keep the dual plane. Thanks for your help!

Michael
