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

Manley Performance has built a solid reputation for making well-built engine components, especially for high-performance applications. This Titanium Exhaust Valve Kit is a prime example of their commitment to optimizing engine power and reliability. 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 periods at high RPMs.

What really sets these valves apart is the material. They're made from a one-piece forged titanium alloy, which is significantly lighter than traditional steel valves. This weight reduction in the valve train helps the engine spin up faster and allows it to reach higher RPMs more safely. The titanium also offers a great balance of strength and ductility needed for high-temperature exhaust service, and Manley uses a special high-temperature alloy for these exhaust valves, indicated by the 'HT' suffix. They also feature inserted hard tips to improve durability where the rocker arm makes contact.

Manley machines these valves with very tight tolerances on advanced CNC equipment, ensuring they perform consistently and reliably. Each valve is meticulously inspected to meet their high standards. This kit includes 8 exhaust valves, each with a 1.625-inch head diameter and a 0.3415-inch stem diameter, measuring 5.140 inches overall length and weighing just 74 grams. This attention to detail means you're getting a well-made component ready for serious performance work.
