Product Details
These Manley Race Series exhaust valves are built from XH-426 stainless steel, a strong material chosen for engines that see a lot of action, especially those running alcohol fuels. They measure 1.600 inches across the head and are 4.911 inches long overall, with a 0.3415-inch stem diameter, making them a solid choice for Ford 289 engines that need reliable performance, particularly under 8000 RPM.
The stems are chrome-plated and feature hard tips to help them hold up to wear over time. You'll also notice the under-head areas are swirl polished and the combustion faces are fully machined. This design work helps improve airflow into the cylinder and can contribute to better combustion efficiency. Manley offers these in different shapes, like the straight stem Race Master or the Race Flo, so you can pick the one that best suits your specific engine build.
