COMP Cams hardened steel street valve locks, 11/32" stem size with four grooves and a 7° angle, are intended as replacement locks for stock engine rebuilds and are recommended for street applications with lighter valve spring loads. Sold as a pair, proper sizing is essential: a small gap between the two halves indicates correct fit while a full closure or excessive gap indicates incorrect lock size.
