Manley Race Master Performance Engine Valve

Manley Race Master performance engine intake valves are built for engine builders who want durable, high-quality stainless steel valves for racing and high-performance street use. The Race Master line is aimed at bracket, drag and oval track engines, and at mild circle track and street performance builds. It uses a straight-stem design, which gives extra stem material for durability. It is a strong choice for anyone replacing stock poppet valves or rebuilding cylinder heads.

Key Features:

• Stainless steel construction: Intake valves are made from NK-842 stainless steel for strength and heat resistance.
• Chrome stems: The chrome finish reduces wear and friction in the valve guide.
• Hardened tips: Hard tips resist wear from rocker arm or lifter contact.
• Swirl-polished under-head area: The polished surface helps air flow smoothly past the valve.
• Fully machined combustion faces: Machining gives consistent quality and a precise seat for reliable sealing.
• Straight-stem design: Similar in purpose to Manley's Race Flo valves, with a straight stem in place of the necked-down profile.

The series is aimed at racers running below about 8,000 RPM. It is a durable, cost-effective alternative to EV-8 alloy valves. Manley has long been a respected name in performance engine components, and Race Master valves give builders a dependable upgrade over stock-style valves.
