Big CAMS

I'm cerently running a stock GSR motor with some bolt ons, CAI, 70mm throttle body, Skunk intake manifold, Toda racing header and cat-back exhaust. But I need more power! Ive been thinking and cams and have three choices. 1. Skunk 2 Stage 2, Toda Racing stage 2, and Crower stage 2. Does anybody have any dyno's with these cams? Or any othe cams? Please help thank you....
