Product Details
These Manley Race Master Series exhaust valves are made from XH-426 stainless steel, a strong material chosen for its ability to handle the heat and stress of high-performance engines. With a 1.88-inch diameter, they are designed for Big Block Chevy applications, specifically for engines that will be running up to 8000 RPM, making them a solid choice for drag, oval track, or bracket racing.
You'll notice the stems are chrome-plated and the tips are hardened, which adds to their wear resistance and helps them last longer in demanding conditions. The under-head areas are swirl polished to help smooth out airflow into the cylinder, and the combustion faces are fully machined. This attention to detail in their construction helps optimize how efficiently the engine breathes and burns fuel. Manley also recommends these for alcohol-fueled engines, where they stand up well to the unique demands of that fuel type.
This set includes eight exhaust valves, and they are the straight stem 'Race Master' style. If you're rebuilding the top end of a performance Big Block Chevy, these valves are built to handle the job.
