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

Manley's titanium exhaust valves start with a one-piece forged construction, a design that uses grain flow to build in durability and avoid the potential weak spots found in head-welded valves. This approach is crucial for engines that will see extended high-rpm use, as it helps the valves withstand the stresses of higher engine speeds and more aggressive camshaft profiles. The titanium alloy itself is carefully selected to balance hardness, ductility, and fatigue strength at the high temperatures these exhaust valves will encounter.

These valves are meticulously machined on advanced CNC equipment, ensuring they meet very tight tolerances for both the stem and head dimensions. With a head diameter of 1.600 inches and a stem diameter of 0.3415 inches, they are designed to fit specific applications within Small Block GM, Ford, and Chrysler engines. Each valve weighs in at a mere 78 grams, a significant reduction compared to steel equivalents, which directly translates to less stress on the entire valve train and allows the engine to rev more freely.

This kit includes a set of 8 valves, providing a complete solution for a V8 engine. Manley puts each valve through a rigorous final inspection to guarantee uncompromising quality and reliability, ensuring that when you install these, you're getting a well-built component ready for demanding performance. If you're building a high-performance engine where every ounce of weight savings and every bit of durability counts, these titanium valves are a solid option.
