Manley Titanium Exhaust Valve Kit - Small Block Chevrolet - All Pro

Starting with the material itself, Manley uses exceptional titanium alloys for these exhaust valves, carefully selected to balance hardness, ductility, and fatigue strength at high temperatures. This isn't just about being light; it's about creating a valve that can handle the demands of aggressive engine builds. The "HT" in the part number specifically tells you these are made from high-temperature material, crucial for keeping things running smoothly under intense heat.

What really sets these apart is the one-piece forged construction. Unlike some other designs that might use welding, Manley's process ensures a solid, durable part with no weak points. They're then meticulously machined in advanced CNC centers to exacting tolerances, ensuring they fit and perform perfectly. With an overall length of 5.950 inches, a 1.600-inch head diameter, and a 0.3110-inch stem diameter, these valves are built for serious performance, especially in high-RPM applications where reducing valve train weight makes a significant difference in engine efficiency and responsiveness. Each valve also features an inserted hard tip and Manley's Bead Loc single radius keeper groove for added reliability.

This kit includes a set of 8 valves, each weighing in at a mere 71 grams, which is a notable reduction compared to standard steel valves. This weight savings can allow your engine to rev higher and more freely. Manley's rigorous quality control means you're getting a product that meets high precision standards, ready for your next engine build.
