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

If you're rebuilding the top end of a Small Block GM, Ford, or Chrysler engine and pushing for serious performance, these Manley Titanium Exhaust Valves are a solid choice. They're built to handle the demands of high-RPM operation, which is crucial when you're aiming for maximum power and responsiveness. By using titanium, Manley significantly cuts down on valve train weight. This reduction means less inertia for your valvetrain components to fight against, allowing for higher engine speeds and improved efficiency.

What really sets these valves apart is their one-piece forged construction. This method ensures a strong, durable part with excellent grain flow, avoiding the potential weak spots you might find in other designs. They're then meticulously machined on advanced CNC equipment to very tight tolerances, ensuring they seal perfectly and perform reliably. Manley uses specific titanium alloys chosen for their balance of strength, hardness, and fatigue resistance, especially at the high temperatures exhaust valves endure. The 'HT' suffix means they're made from high-temperature material, and they even have inserted hard tips to stand up to the valve seat over time.

This kit includes a set of 8 exhaust valves, each weighing around 85 grams, with a head diameter of 1.625 inches and a stem diameter of 0.3415 inches. They are designed for applications that regularly see extended high-RPM use. Because these are specialized performance parts, it's always a good idea to consult your engine builder or a trusted mechanic to ensure they fit your specific build plans and camshaft profiles.
