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

Manley Performance has built a solid reputation for making well-built engine components, and their Titanium Exhaust Valves are a prime example of that commitment. If you're working on a Small Block GM, Ford, or Chrysler engine and pushing the limits with high-RPM operation or aggressive camshafts, these valves are designed to handle that kind of stress. They're all about reducing the weight in your valvetrain, which helps your engine spin faster and more efficiently.

What sets these apart is their one-piece forged construction. This method, combined with careful grain flow, creates a stronger, more reliable valve than those made with welded heads. Manley uses top-tier titanium alloys, chosen specifically for their balance of hardness, ductility, and fatigue strength at high temperatures. Each valve is then precisely machined in advanced CNC centers to exacting tolerances, ensuring they seal perfectly and perform consistently. The result is a significant reduction in valvetrain mass, allowing for higher engine speeds and improved overall performance.

This kit includes eight exhaust valves, each weighing in at a mere 74 grams, with a head diameter of 1.600 inches and a stem diameter of 0.3415 inches. Manley puts every valve through a rigorous final inspection to guarantee uncompromising quality and reliability. When you're building an engine that needs to perform under pressure, these titanium valves are a smart choice for durability and speed.
