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 the limits with high-RPM operation, these Manley Titanium Exhaust Valves are a serious consideration. They're designed to significantly reduce the weight in your valve train, which is crucial when you're aiming for higher engine speeds and need the valvetrain to keep up reliably.

What sets these apart is their one-piece forged construction. This method ensures a solid, durable part with consistent grain flow, avoiding the potential weak points found in other designs. Manley uses specific titanium alloys chosen for their balance of hardness, ductility, and fatigue strength at the high temperatures exhaust valves endure. They're then meticulously machined on advanced CNC equipment to very tight tolerances, ensuring each valve seals perfectly and performs consistently.

This kit includes 8 exhaust valves, each weighing in at just 73 grams, with a head diameter of 1.600 inches and a stem diameter of 0.3415 inches. The overall length is 5.060 inches. Because these are specialized performance components, it's always a good idea to consult with your engine builder or refer to Manley's installation guidelines to ensure proper setup with your specific camshaft and valvetrain components.
