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

Manley titanium exhaust valves are forged from advanced titanium alloys, a material choice that significantly cuts down on weight compared to traditional steel valves. This reduction in mass is crucial for high-rpm engine builds, as it lessens the stress on the entire valve train, allowing for higher engine speeds and better responsiveness. The one-piece forged construction with controlled grain flow adds to their durability, creating a solid component that's less prone to failure under demanding conditions than welded alternatives.

These valves are meticulously machined on CNC equipment to ensure they meet very precise tolerances, which is essential for a good seal and efficient operation. The specific titanium alloys Manley uses are selected to balance hardness, ductility, and fatigue strength, especially important when an engine is running at high temperatures and speeds for extended periods. Each valve goes through a thorough final inspection to guarantee it meets Manley's high standards for performance and reliability.

This kit includes eight exhaust valves, each measuring 1.600 inches in head diameter, with a 0.3415-inch stem diameter and an overall length of 5.260 inches. They weigh in at a light 77 grams each, making them a popular choice for racers and builders focused on optimizing performance in small block GM, Ford, and Chrysler engines.
