Manley Race Master Stainless Steel Engine Valve

Manley Race Master stainless steel engine valves are performance intake valves built for bracket, drag and oval track racing. They also suit modified street engines. They are designed for engines that run below about 8,000 rpm. Above that speed, titanium valves are generally the better choice. Builders who use EV-8 (21-4N) alloy valves will find this series a strong alternative.

Key Features:

• NK-842 stainless steel is used for intake valves. The Race Master line uses XH-426 for its exhaust valves.
• Chrome stems and hard tips add wear resistance and longevity. The hard tips are meant to resist cracking and eroding, which can happen with puddled stellite tips.
• Swirl-polished under-head area and fully machined combustion face help optimize airflow and combustion efficiency.
• Better fatigue strength for durability under hard racing use.

Manley is a well-known maker of performance valvetrain and engine components. Race Master valves give engine builders a durable, cost-effective stainless valve for high-performance and racing builds.
