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

Manley titanium exhaust valves are forged from exceptional titanium alloys, striking a balance between hardness, ductility, and fatigue strength at high temperatures. The 'HT' suffix specifically indicates high-temperature material, making these valves well-suited for demanding engine builds. Each valve features a one-piece forged construction with grain flow, which is a more durable design than head-welded alternatives and minimizes potential weak points. This advanced construction, combined with meticulous machining in state-of-the-art CNC centers, ensures they meet exacting tolerances for optimal performance.

The primary benefit of using titanium is significant weight reduction in the valve train. This lower mass allows for improved engine efficiency and is particularly advantageous in high-rpm applications. If you're building an engine that will spend a lot of time at higher engine speeds, or if you're using aggressive camshaft profiles, these valves can help accommodate those demands. The valves also feature inserted hard tips for added durability where the rocker arm makes contact.

This kit includes eight exhaust valves, each weighing approximately 80 grams, with a head diameter of 1.625 inches and a stem diameter of 0.3415 inches, for an overall length of 5.560 inches. Manley Performance Products puts each valve through a stringent final inspection process to ensure uncompromising quality and reliability. Strict quality control measures allow for delivery within tight tolerances, meeting the highest precision standards for your engine build.
