...what cams i have. I just purchased a gsr, and it is way too fast to just have bolt ons. so i popped the valve cover and i was just looking around, and it was way too clean (i think) to not have head work done. it was spotless. anyway, im positive it has aftermarket cams, but i do not know how to tell which cams they are. so how can i tell? sorry for the noob question....
