just do a swap...... i wouldnt really mess with cams unless you know and understand the lifts and durations of teh stock lobes and whatever else you plan on using, aswell as tolerances for the journals on the head... you dont wanna just slap a cam in run it and have it get starved for oil you know?[xx(]thatwould be a costly boo boo. If you wanna play wit the cams look into buying a cam gear from ape and sending em yours to press an adujstable one on sos you can pay a tuner to adjust your timing that way. But again just do a swap its the best bang for the buck in all scenarios bikes cars whatever.
