I'd recommend a copy of PipeMax to help with the cam selection. You have head flow data and dyno data so PipeMax should be able to add the next level of information. I'm thinking you could reduce your cam duration by 20 degrees and have a better overall combination.

Post your combo over on SpeedTalk and ask for a cam recommendation. I bet that Mike Jones tells you something in the 250 range with 650+ lift. But who knows, sometimes he surprises me.
