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

Manley Performance has built a solid reputation for making well-built engine components, and their Titanium Exhaust Valve Kit is a prime example of that commitment. If you're working on a high-performance Small Block GM, Ford, or Chrysler engine, especially one that's going to see a lot of time at high RPMs, these valves are worth a close look. They're designed to help your engine breathe better and rev higher by significantly reducing the weight in your valvetrain.

What really sets these apart is the one-piece forged construction. Unlike some other designs that might use welding, Manley forges these valves from exceptional titanium alloys, ensuring there are no weak points. This process also aligns the grain flow for added durability. They're then meticulously machined on advanced CNC equipment to very tight tolerances, ensuring each valve seals perfectly and performs consistently. The specific titanium alloys Manley uses are chosen for a good balance of strength, hardness, and fatigue resistance, which is crucial when an engine is running hard for extended periods.

This kit includes eight exhaust valves, each weighing around 80 grams, with a head diameter of 1.600 inches and a stem diameter of 0.3415 inches. The overall length is 5.560 inches. Manley puts each valve through a strict final inspection to make sure you're getting a reliable part that meets their high standards. If you're building an engine where every ounce counts and you plan on pushing the limits, these titanium valves are a strong choice.
