I don't think you're going to need to shift any higher than 6,500 RPMs to get the max power out of your car. It's really going to be completely pointless to go any higher than 6,500 RPMs. I'd shoot for around 6,300-6,500 RPMs. Mickey has SPR cams which are going to make power all the way up into 7,000+ RPMs.
