Difference in Victor and Super Victor Intake

I've got a Super Victor on my race motor. 10:1, 365", CNC IndyBrock heads, 249* @.050 .712 roller. Super Vic made 587 peak HP with a 2" wilson taper spacer, RPM AirGap with 1" open spacer made 541 HP. Don't really think I'm even tapping the potential of this intake. IMO its better off on big inch strokers capable of 600+ HP. Port exits are cast small for port matching, not a use out of the box deal.
