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

When you're building a high-performance engine that needs to spin up fast and hold high RPMs, the weight of your valvetrain components really matters. This kit from Manley Performance includes eight titanium exhaust valves, specifically designed to cut down on mass. You get the actual valves in this set, ready to be installed in your Small Block GM, Ford, or Chrysler engine.

Manley makes these valves from a one-piece forged titanium alloy, which is a strong choice for durability and minimizing potential failure points. They're precisely machined using advanced CNC equipment to ensure they meet tight tolerances, which is crucial for consistent engine operation, especially at higher speeds. The titanium used is chosen for a good balance of hardness and ductility, even at high temperatures, and these particular valves have an "HT" suffix indicating they're made with high-temperature material. They also feature inserted hard tips for added durability where the rocker arm makes contact.

With a head diameter of 1.625 inches and a stem diameter of 0.3415 inches, these valves are designed for specific applications where reducing weight is key to achieving higher engine speeds and better overall efficiency. Each valve weighs in at about 80 grams, significantly less than comparable steel valves. Manley puts each valve through a strict final inspection to make sure they meet their high standards for reliability and performance.
