.308 Cc Super Valve Lock 10 Deg-W/Lash Cap Recess

The COMP CAMS .308 Caliber Super Valve Lock with 10-degree angle and lash cap recess (model 610-16) is a precision engine component designed for serious small-block and big-block performance builds. These hardened steel valve locks feature black oxide coating for corrosion resistance and are engineered to securely retain valve springs under high rpm and high-lift camshaft loads. The 10-degree geometry and integrated lash cap recess accommodate modern valve spring assemblies while maintaining the critical interface between rocker arm and valve stem.

Specification highlights include a 5/16-inch valve stem size and standard height design, ensuring drop-in compatibility with common small-block applications. The lash cap recess is machined to accept adjustable rocker arms and valvetrain geometry that demands precision clearancing. COMP CAMS valve locks are manufactured to tight tolerances—critical for preventing valve stem movement and retainer rotation during peak cylinder pressures. The set of 16 locks provides coverage for eight cylinders with redundancy for rebuild and replacement scenarios. Black oxide finish resists oxidation in engine bay environments where moisture and heat cycling accelerate corrosion on uncoated steel.

This product is essential for engine builders, performance shops, and enthusiasts assembling or refreshing cylinder heads with aftermarket camshaft upgrades. Super valve locks accommodate more aggressive lift profiles than stock components, making them a must-have for any valvetrain expecting elevated spring pressures. Whether building a street performance engine or race-ready platform, using the correct valve lock geometry and material ensures reliability and eliminates the risk of catastrophic valve stem failure.

COMP CAMS is recognized in the industry for precision valve train components engineered to deliver consistent performance across diverse engine platforms. Selecting proper valve locks—matching diameter, angle, and valve stem size—is non-negotiable in high-performance engine assembly and directly impacts engine longevity and safety.
