Product Details
If you're building a high-performance Big Block Chevrolet engine for demanding applications like Top Fuel drag racing or marine use, you need parts that can handle extreme force and heat. This Manley Extreme Duty exhaust valve is designed specifically for those kinds of tough jobs. It's a single valve, so you can replace them one by one as needed for your rebuild.
What sets this valve apart is its XH-432 XtremeAlloy construction, a material chosen for its exceptional heat and force resistance. It also features a chrome stem and a hard tip, which adds to its longevity and wear resistance, meaning it'll hold up better over time. The under-head area is swirl polished to help improve airflow, and the machined combustion face is designed to boost combustion efficiency. These details add up to a valve that's built to perform when you push your engine hard.
