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

If you're rebuilding the top end of a Small Block GM, Ford, or Chrysler engine and pushing the limits with high-RPM operation, these Manley Titanium Exhaust Valves are a serious consideration. They're built to handle the demands of aggressive camshaft profiles and extended periods at high engine speeds, where reducing reciprocating mass becomes critical for reliability and performance. By shedding significant weight compared to traditional steel valves, these titanium pieces help your valvetrain keep up, preventing float and ensuring consistent valve control when you're deep in the powerband.

Manley crafts these valves from exceptional titanium alloys, chosen for their specific balance of hardness, ductility, and fatigue strength at elevated temperatures. The one-piece forged construction with integrated grain flow adds a layer of durability that you won't find in head-welded alternatives, minimizing potential failure points. Each valve is then meticulously machined in advanced CNC centers to exacting tolerances, ensuring a precise fit and optimal sealing. The 'HT' designation means they use high-temperature alloys, and they also feature inserted hard tips for added wear resistance where it matters most.

This kit includes a set of eight exhaust valves, each weighing in at a mere 87 grams, with a head diameter of 1.625 inches and a length of 5.660 inches. Manley's rigorous quality control process, from material selection to final inspection, means you're getting a well-built component ready for demanding applications. While these are designed for high-RPM use, their precise machining and durable materials make them a solid choice for any performance build where reducing valvetrain weight is a priority.
