Competition Cams Super valve locks are wider-angled 10 degree locks. They distribute the ever-increasing valve spring loads over the retainer better than typical 7 degree locks by reducing the chance of "pull-through" failure. These valve locks are precision-machined for accuracy and are available for many popular valve sizes with or without a lash cap recess. The Super valve locks will fit any Comp Cams 10 degree retainer and are recommended for all race applications due to their superior strength. (Set of 16)
