COMP Cams Valve Locks Hi Perf For Gm LS

These single groove Machined Steel Street Locks with 7? lock angle and 8mm valve stem size are perfect locks for GM Gen III/LS1/LS2/LS6 applications. It is critically important to make sure valve locks match the valve size. There should always be a small gap between the two halves of the lock when they are properly positioned on the valve stem. If the two halves fit together without a gap, they are too large. If the locks fit tight to the stem and leave a gap between the middle of the lock and the O.D. of the stem, the locks are too small.
