COMP Cams hardened steel street locks, 11/32" stem size with four grooves and a 7° angle, are supplied as 16 pairs in this set. Recommended for street applications with lighter valve spring loads, the locks must match valve stem size and leave a small gap between the two halves when correctly positioned so the retainer taper can bind them together securely during operation.
