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

If you're building a high-performance small block engine for GM, Ford, or Chrysler, these Manley Titanium Exhaust Valves are a serious consideration. They're designed to cut down on valve train weight, which is crucial when you're pushing the engine to higher RPMs. Reducing that mass helps the valvetrain keep up, allowing for more aggressive camshaft profiles and extended periods at high engine speeds.

What sets these apart is their one-piece forged construction. This method ensures a strong, durable valve with consistent grain flow, avoiding the potential weak spots you might find in other designs. Manley uses top-tier titanium alloys specifically chosen for their balance of hardness, ductility, and fatigue strength at the high temperatures these valves will see. They're then meticulously machined on advanced CNC equipment to very tight tolerances, ensuring they perform exactly as they should right out of the box. Each valve is checked rigorously to meet Manley's high standards for reliability.

This kit includes eight exhaust valves, each weighing in at a mere 74 grams. They feature a 1.625-inch head diameter, a 0.3415-inch stem diameter, and an overall length of 5.060 inches. The stem has a groove for the retainer lock. When you're aiming for maximum performance and need to shave weight from the valvetrain, these titanium valves are a well-built choice.
