skunk2 stage 1 cams are better and more aggresive then both i don't know who is telling u that they are not!, and i had them on my GSR with stock valve train and i never had any issues at all!, and also stage2 unless u plan on doing shit to your bottom end will not give u much more hp and your idle is not going to be as nice. SKunk2 stage 1 cams are your best bet, and u know if u want them were to find me cause i got them for sale!
