Manley Performance Race Master Stainless Steel Valves Engineered for racing , Manley Performance Race Master valves deliver durable, high-flow performance for competition engines. Built from premium stainless steel with chrome-plated stems and hard tips, these valves resist wear and tolerate extreme temperatures and fuels. Premium stainless steel construction — superior strength and corrosion resistance for both intake (NK-842) and exhaust (XH-426) applications. Chrome stems & hard tips — reduced stem wear, enhanced valve guide compatibility, and long service life under high rpm and heavy load. Swirl-polished under-head — improved gas flow and reduced turbulence for better cylinder filling and combustion efficiency. Fully machined combustion faces — precise sealing and consistent performance across demanding race conditions. Multiple shapes available — choose Race Master (straight stem) or Race Flo profiles to match valve train geometry and airflow targets. Recommended for alcohol engines — especially suited for exhaust duties where high heat and corrosive fuels are common. Ideal for builders and racers seeking reliable, race-proven valvetrain components, Manley Race Master valves combine advanced finishing, material choice, and design flexibility to maximize power and durability.
