The MANLEY 7 Degree Valve Locks (MAN13083-16) are precision-engineered components designed for high-performance engine builders and mechanics seeking reliable valve train control. These locks are essential for any serious head work, custom engine build, or high-rpm application where maintaining consistent valve geometry is critical.
The 7-degree angle design is engineered to work harmoniously with modern valve spring geometries and kerf configurations, providing superior retention of the valve stem and reducing the risk of valve rotation or loss at high rpm. MANLEY's manufacturing precision ensures tight tolerances and consistent fit across the entire set, eliminating the binding or slippage that can occur with lower-quality aftermarket locks.
These valve locks benefit engine builders working with aftermarket cylinder heads, competition engines, and modified street motors where reliability under sustained high-rpm operation is non-negotiable. The compact profile and lightweight construction make these locks suitable for both small-block and large-block engine platforms, depending on the specific valve stem diameter and spring pocket configuration of your cylinder head.
