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

Forged from exceptional titanium alloys, these Manley exhaust valves are built to handle the demands of high-rpm engine operation. Their unique material choice significantly reduces valve train weight, which is crucial for improving engine efficiency and allowing for higher engine speeds, especially when paired with aggressive camshaft profiles. This kit is specifically designed for small block applications across GM, Ford, and Chrysler platforms.

Manley's one-piece forged construction ensures maximum durability by maintaining consistent grain flow throughout the valve, avoiding potential weak points found in head-welded designs. Each valve is meticulously machined in advanced CNC turning centers and valve stem grinders, holding exacting tolerances for optimal performance and sealing. The titanium alloys used are selected for a precise balance of mechanical properties, hardness, ductility, and fatigue strength at elevated temperatures, making them ideal for performance builds.

Every valve in this kit undergoes a rigorous final inspection process, ensuring uncompromising quality and reliability. This strict quality control allows Manley to deliver valves within tight tolerances, meeting the highest precision standards required for serious engine work. The kit includes eight exhaust valves, each weighing approximately 77 grams, with a 1.600-inch head diameter, a 0.3415-inch stem diameter, and an overall length of 5.460 inches.
