Manley Chrysler Top Fuel Exhaust Valve Kit - 1.950in Head Dia. 5.120in O/A Length, 0.3715in Stem

The XH-432 XtremeAlloy material used in these Manley Chrysler Top Fuel exhaust valves is a key indicator of their intended use: extreme force and heat resistance. This isn't your average street engine part; these valves are built for the punishing environment of Top Fuel and Funny Car drag racing, as well as high-performance marine applications. If your build demands components that can withstand immense pressure and temperatures, these valves are designed to meet that challenge.

Beyond the advanced alloy, Manley has incorporated several features to ensure longevity and optimized performance. The chrome stems offer improved wear resistance, while the hard tips stand up to the impact of valve train operation. You'll also find swirl polished under-head areas and fully machined combustion faces. This attention to detail in the machining helps improve airflow into the combustion chamber and contributes to better combustion efficiency, which is critical when you're pushing an engine to its limits.

When you're working on a high-horsepower build that requires specialized components, having parts like these Manley valves can make a significant difference. They are sold as a kit, and while the specific contents aren't detailed here, you can expect them to be manufactured to the high standards Manley Performance is known for. Remember to consult Manley's official documentation for the exact number of valves included in this kit and any specific installation requirements for these specialized components.
