Review MANLEY Severe Duty Exhaust Valves

The Manley 11817-8 Severe Duty Exhaust Valves are a high-performance upgrade for racing and high-performance applications. These valves are designed to withstand the extreme conditions found in high-rpm, high-boost, and high-heat environments.

The valves are made from a special alloy called 316L Stainless Steel, which provides superior strength and durability compared to standard valves. The valve stems are also made of this material, ensuring a strong connection to the valve guide and reducing the likelihood of valve float or stretch.

The valves feature a unique design with an increased valve seat angle, which provides improved sealing and reduces the risk of carbon build-up. The valve heads are also CNC-machined to ensure a precise fit and optimal flow.

The Manley 11817-8 Severe Duty Exhaust Valves are available in various sizes to fit different engine applications, and they are designed to work with both overhead cam (OHC) and pushrod (PR) engines. The valves come with new valve springs and retainers, making this a complete valvetrain upgrade.

These valves are ideal for use in high-performance applications such as racing, hot rods, and high-boost turbocharged engines. They are also a popular choice for builders who are looking to maximize power and reliability in their engine build.

The Manley 11817-8 Severe Duty Exhaust Valves are not just an upgrade for power, but they also offer improved engine durability and reliability. Their superior strength and design make them a worthy investment for any high-performance engine build.
