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

Manley Performance has built a solid reputation for making well-built engine components, and these titanium exhaust valves are a prime example of their commitment to performance. If you're building a high-revving small block engine for your GM, Ford, or Chrysler vehicle, these valves are designed to handle the demands of aggressive camshafts and extended high-rpm operation. They're a key part of optimizing your engine's efficiency and allowing it to spin faster and more freely.

What sets these valves apart is their one-piece forged construction. This method, combined with careful grain flow management, creates a stronger, more durable valve 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, ensuring they hold up under pressure. Each valve is meticulously machined on advanced CNC equipment to very tight tolerances, ensuring they seal properly and perform consistently. The 'HT' in the part number signifies high-temperature material, and these valves also feature inserted hard tips for added durability.

This kit includes a set of 8 exhaust valves, each measuring 1.600 inches in head diameter, 0.3415 inches in stem diameter, and 5.560 inches in overall length. They are available with either conventional square keeper grooves or Manley's BeadLoc single radius keeper grooves, so you can choose the style that best suits your valvetrain setup. Rigorous quality control ensures you're getting a reliable component ready for serious use.
