What is the main function of a valve lock?

The main function of a valve lock, along with the retainer, is to hold the valve spring in place. The retainer's taper creates a collet effect that binds the lock and retainer together, securing the valve spring assembly.

How do I know if these valve locks are the correct size for my valves?

When properly installed, there should be a small gap between the two halves of the valve lock. If the halves fit together with no gap, they are too large. If they fit tightly and leave a gap between the middle of the lock and the valve stem's outer surface, they are too small.

Do these valve locks require special retainers?

No, these 7-degree valve locks are designed to work with standard retainers. You do not need to switch to 10-degree retainers for these locks to function correctly.

Product Details

COMP Cams is well-known for making performance engine parts that help you get the most out of your build. For your 1997-2002 Chevrolet Corvette, these high-performance valve locks are a critical piece for ensuring your engine runs smoothly and reliably, especially when you're pushing it hard. While many people think the tang on a valve lock holds everything together, it's actually the retainer's taper that creates a collet effect, binding the lock and retainer. The harder your valve springs work, the tighter this connection becomes, keeping your valve train secure.

This set includes 100 machined steel valve locks, designed with a 7-degree angle and a single groove, suitable for 8mm valve stems. It's important that the valve locks match your valve size precisely. When installed correctly, there should be a small gap between the two halves of the lock. If they fit together with no gap, they're too large, and if they leave a gap between the middle of the lock and the stem's outer surface, they're too small. These locks are built for performance applications, offering accurate valve spring location.

For your specific application, these 7-degree locks are a solid choice. They are designed to work with standard retainers, so you don't need to switch to 10-degree retainers. Make sure to check that these locks are the correct size for your valves to ensure a proper fit and optimal performance.
