Description
Valve locks are critical to maintaining proper valve train geometry and preventing valve float at high RPM—especially in forced induction or solid-lifter applications where spring pressures demand precision. Manley’s 7-degree geometry locks provide the shallow angle necessary for modern cylinder head designs while maintaining rock-solid retention. This set of 32 ensures you have spares for future builds or complete engine refreshes.
