Manley Titanium Exhaust Valve Kit - Big Block Chevrolet - Brodix SR20 - Dart 20 Degree

Manley Performance has built a reputation for well-made engine components, and their titanium exhaust valves are a prime example of that commitment. If you're working on a Big Block Chevrolet engine, especially one fitted with Brodix SR20 or Dart 20 Degree heads, these valves are designed to help you extract maximum performance. They are specifically engineered to reduce the overall weight in your valve train, which is crucial for allowing your engine to safely reach and sustain higher revolutions per minute. This makes them a great choice for aggressive camshaft profiles and demanding high-rpm operation.

What sets these valves apart is their one-piece forged construction. This method ensures a solid, durable part with consistent grain flow, avoiding the potential weak points found in head-welded alternatives. Manley utilizes exceptional titanium alloys, carefully selected for their balance of hardness, ductility, and fatigue strength at elevated temperatures. Each valve is then meticulously machined on advanced CNC equipment to exacting tolerances, ensuring they meet the highest precision standards for optimal performance. You'll find they feature Manley's Bead Loc single radius keeper grooves, and remember that tip protection is required for these valves.

This kit includes eight exhaust valves, each with a 1.800-inch head diameter and a 0.3415-inch stem diameter, with an overall length of 6.010 inches. The rigorous quality control Manley applies throughout the manufacturing process means you're getting a reliable component built for performance. When you're aiming for peak engine efficiency and high-rpm capability, these titanium valves are a solid option to consider for your build.
