Crow Cams Square Groove Std Height Machined Valve Locks - Set of 16 pairs
Square Groove Std Height Machined Valve Locks - Set of 16 pairs — 4133-16
Sixteen pairs of machined valve locks for 11/32-inch stems. The design uses a single square groove, 7-degree taper and standard height.
Crow lists compatible Holden V8, small-block Chevrolet, Cleveland, Windsor and Ford 429–460 valve applications. Verify the matching retainer before fitting.
Applications and compatibility
This part is listed for the following engine and vehicle applications where the Crow camshaft or valvetrain package calls for this exact part number:
- Holden Commodore VN–VR — 5.0L EFI V8
- Holden Commodore VS — 5.0L EFI V8
- Holden Torana LH–UC — V8 applications
Compatibility is still determined by the complete cylinder-head and camshaft combination; vehicle model alone is not a substitute for checking the required spring, retainer, lock, lifter and rocker setup.
Installation checks
Confirm valve-stem diameter, valve-groove style, retainer taper and the intended installed-height change before fitting. Locks, retainers and valves must be treated as one matched system.
