Manley Titanium Exhaust Valve Kit - Big Block Chevrolet - M&M X20

Manley Performance is well-known for making strong engine components, and their titanium valves are a prime example of that commitment. If you're building a high-performance Big Block Chevrolet engine, especially one that will see extended time at high RPMs, these Manley Titanium Exhaust Valves are designed to help you get the most out of your build. They're engineered to reduce the overall weight of your valve train, which is crucial for allowing the engine to spin faster and more reliably.

What sets these valves apart is their one-piece forged construction. This method, combined with careful grain flow management, creates a more durable part than those made with head-welding techniques, minimizing potential failure points. Manley uses exceptional titanium alloys specifically chosen for their balance of hardness, ductility, and fatigue strength at high temperatures. Each valve is then meticulously machined on advanced CNC equipment to very tight tolerances, ensuring they perform exactly as intended. The Bead Loc? single radius keeper grooves are a notable detail, designed for secure installation.

Because these are high-performance parts intended for demanding use, Manley requires tip protection for these valves. They also offer variations with higher hardness material, indicated by an 'H' suffix, and some without a hard tip. Always ensure you're using the correct type and installation method as recommended by Manley for your specific application. This set includes 8 exhaust valves, each with a 1.850-inch head diameter and a 0.3110-inch stem diameter, measuring 5.975 inches overall.
