Manley Big Block Ford 429-460 1.880in Diameter 5.655in Length Race Master Exhaust Valves (Set of 8)

Manley Performance is well-known for making strong internal engine components, and these Race Master exhaust valves are a prime example. If you're rebuilding the top end of your Big Block Ford 429 or 460 engine, these valves are built to handle the stress of racing applications, especially those running up to 8000 RPM.

These exhaust valves are made from stainless steel, which gives them solid durability. They also feature chrome stems and hard tips to help them last longer and resist wear, even under tough conditions. The under-head areas are swirl polished and the combustion faces are fully machined. This design helps improve airflow into the cylinder and makes combustion more efficient. Manley offers these in a Race Master straight stem design, which is a popular choice for many racing engines, and they are specifically recommended for use in alcohol-fueled engines.

This set includes eight exhaust valves, so you'll have what you need to replace all of them in your engine. Make sure to check the manufacturer's installation instructions for any specific procedures or requirements when installing these valves.
