Review MANLEY Race Master/severe Duty Exhaust Valves

Introducing the Manley Race Master/Severe Exhaust Valves, a high-performance solution for racers and hot rod enthusiasts seeking superior durability and reliability in their exhaust systems. These valves are specifically designed to withstand the extreme conditions and high temperatures encountered in racing applications.

The Manley Race Master/Severe Exhaust Valves feature a unique construction that sets them apart from standard OEM valves. The valves are made of nickel-chromium steel alloy, which provides excellent strength and resistance to thermal fatigue. This material is also known for its ability to maintain its shape under extreme temperatures, reducing the risk of valve distortion and failure.

The valves come in a 1.6:1 rocker arm ratio and are available in various sizes to accommodate various engine applications. Each valve is individually inspected and tested to ensure optimal performance and durability.

These valves also feature a unique design that allows for larger valve sizes, which can lead to increased airflow and improved engine performance. The valves also have a longer stem length, which provides better clearance for high-lift camshafts and larger valve springs.

The Manley Race Master/Severe Exhaust Valves also come with a unique valve seat design. The seats are made of stainless steel and are angled to help reduce the possibility of carbon build-up and sticking, leading to smoother operation and longer valve life.

These valves are also designed to work seamlessly with aftermarket exhaust systems, making them an excellent choice for custom builds and high-performance applications. They are also compatible with most aftermarket valve springs and retainers, providing flexibility for builders to choose the components that best suit their specific application.

In summary, the Manley Race Master/Severe Exhaust Valves are a high-performance solution for racers and hot rod enthusiasts seeking superior durability and reliability in their exhaust systems. With their unique construction, larger valve sizes, and compatibility with aftermarket components, these valves offer excellent performance and versatility for those seeking to build the ultimate high-performance engine.
