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

If you're building a high-performance small block engine for GM, Ford, or Chrysler, these Manley Titanium Exhaust Valves are a serious consideration. They're designed to shave significant weight off your valve train, which is crucial for allowing your engine to rev higher and more reliably. When you're pushing an engine hard, especially at extended high-RPMs, reducing the mass that the valvetrain has to control makes a big difference in how well it performs and how long it lasts.

What sets these apart is their one-piece forged construction. This method ensures a solid, durable part with consistent grain flow, avoiding potential weak spots you might find in other designs. Manley uses specific titanium alloys chosen for their balance of hardness, ductility, and fatigue strength at the high temperatures these valves will see. They're then machined to very tight tolerances on advanced CNC equipment, ensuring each valve seals perfectly and operates smoothly. This attention to detail means you're getting a well-built component that's ready for aggressive camshaft profiles and demanding use.

This kit includes a set of 8 exhaust valves, each weighing in at a mere 78 grams. The head diameter is 1.600 inches, with a 0.3415-inch stem diameter and an overall length of 5.560 inches. Manley puts each valve through a rigorous final inspection to make sure they meet their high standards for performance and reliability. If you're aiming for maximum performance and durability in your small block build, these titanium valves are a solid choice.
