Description
Valve locks are critical components that keep your valve retainers securely seated under extreme combustion pressures and high RPM conditions. Manley’s 10-degree bead loc design provides superior retention geometry, while the +.050″ height specification accommodates custom cylinder heads and high-lift cam applications. If you’re running forced induction, aggressive valve timing, or competing at the track, precision valve locks are non-negotiable for reliability.
