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

If you're rebuilding the top end of a small block GM, Ford, or Chrysler engine and pushing the limits with high-RPM operation or aggressive camshafts, these Manley Titanium Exhaust Valves are a serious consideration. They're designed to significantly cut down on valve train mass, which is crucial for allowing your engine to spin faster and more reliably at elevated speeds. Reducing that reciprocating weight helps the entire valvetrain keep up, preventing float and ensuring consistent valve control when you're really asking a lot from your engine.

What sets these apart is their construction. Manley uses a one-piece forged titanium alloy, which is not only incredibly light but also very strong and durable, especially at high temperatures. This forged process ensures a consistent grain flow, making them more robust than welded alternatives. They're then precisely machined on advanced CNC equipment to very tight tolerances, ensuring they seal and perform exactly as they should. The titanium alloy is chosen for a specific balance of hardness, ductility, and fatigue strength needed for demanding exhaust valve applications.

This kit includes eight exhaust valves, each weighing around 75 grams, with a head diameter of 1.625 inches and a 5.060-inch overall length. The "HT" suffix means they're made from high-temperature material, and they feature inserted hard tips for added durability where the rocker arm makes contact. Each valve is put through a rigorous final inspection to ensure they meet Manley's high standards for performance and reliability.
