Manley Titanium Exhaust Valve Kit - Small Block GM, Ford, Chrysler

Manley titanium exhaust valves are forged from exceptional titanium alloys, striking a perfect balance between mechanical properties, hardness, ductility, and fatigue strength at specific temperatures. These valves are designed with one-piece forged construction and grain flow, which ensures durability and minimizes potential weak points compared to head-welded alternatives. Each valve is meticulously machined in state-of-the-art CNC turning centers and valve stem grinders, maintaining exacting tolerances for optimal performance. The head diameter measures 1.600 inches, with a stem diameter of 0.3415 inches and an overall length of 5.160 inches. These valves are ideal for reducing valvetrain weight, improving engine efficiency, and enhancing overall performance, especially in high-rpm and extended high-rpm applications, allowing for higher engine speeds and compatibility with aggressive camshaft profiles.

Manley utilizes the finest titanium alloys for these exhaust valves, chosen for their durability and ability to perform under demanding conditions. Strict quality control measures are in place throughout the manufacturing process, from the initial forging to the final inspection, ensuring uncompromising quality, performance, and reliability. This rigorous process enables the delivery of valves within tight tolerances, meeting the highest precision standards required for serious engine builds. Each valve weighs just 74 grams, contributing significantly to valvetrain weight reduction. This kit includes a set of 8 valves, designed to fit Small Block GM, Ford, and Chrysler engines.
