Question is in the title, did a search and did not turn up anything solid.

These would be going into a vortech 350z, initially revving to 6600 but later on revving higher, all input/advice is welcome and appreciated.

 

I think the BC website has power/torque curves for the stage 2 and 3 cams. Check to see if they are still there. Also, I think there was some discussion as to the differences a while back, maybe in a thread from about a year ago. If you can find that thread, it would be worth reviewing too.

 

For a vortech setup, definitely stick with the stage 2 264's. They would be a good match. If you have an efficient setup and are targeting 8000+rpm , then I would recommend looking at a more aggressive cam. FYI, we stock these cams and have used them (264 and 272) in numerous builds.
