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

This kit gives you a set of eight Manley Titanium Exhaust Valves, designed for performance small block engines from GM, Ford, and Chrysler. These valves are a key component in your engine's breathing system, controlling the flow of exhaust gases out of the combustion chamber. By using titanium, Manley significantly cuts down on the weight of the valve train, which is crucial for engines that need to spin at high RPMs without valve float.

Manley makes these valves from a single piece of forged titanium alloy. This method ensures a strong, durable part with consistent grain flow, avoiding potential failure points found in welded designs. They're precisely machined on advanced CNC equipment to very tight tolerances, meaning they'll seal well and operate smoothly. The specific titanium alloy Manley uses is chosen for its balance of hardness, ductility, and strength at high temperatures, making these valves well-suited for demanding, high-rpm applications and aggressive camshafts.

Each valve measures 1.600 inches in head diameter, has a 0.3415-inch stem diameter, and an overall length of 5.060 inches, weighing in at just 75 grams. Manley puts every valve through a strict final inspection to ensure they meet high standards for performance and reliability. If you're building an engine that needs to perform at high RPMs, these lightweight titanium valves are a solid choice to help reduce valve train mass and improve overall engine efficiency.
