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

When you're building a high-performance engine that needs to spin up fast and hold high RPMs, every ounce of weight savings counts. This kit from Manley Performance includes eight titanium exhaust valves, specifically designed to reduce the overall weight of your valve train. This reduction is crucial for improving engine efficiency and allowing for higher engine speeds, especially when paired with aggressive camshaft profiles.

Manley makes these valves from a one-piece forged titanium alloy, which is a strong choice for durability and minimizing potential failure points compared to other construction methods. They're machined with precision in advanced CNC centers to very tight tolerances, ensuring they perform exactly as they should. The specific titanium alloy Manley uses offers a good balance of hardness, ductility, and fatigue strength needed for the demanding temperatures and stresses inside an engine. Each valve is put through a strict final inspection to make sure you're getting a reliable part.

This set includes eight exhaust valves, each with a 1.625-inch head diameter, a 0.3415-inch stem diameter, and an overall length of 5.160 inches. They feature a groove for the bead lock. Each valve weighs in at about 75 grams, contributing to that important weight reduction for your engine build.
