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, these Manley Titanium Exhaust Valves are a serious consideration. They're designed to significantly cut down on valve train weight, which is crucial for allowing your engine to spin faster and more reliably at extended high engine speeds. This also helps when you're running aggressive camshaft profiles that demand a responsive valvetrain.

What sets these apart is their one-piece forged construction. This method, combined with careful grain flow management, creates a stronger, more durable valve compared to those made with head-welded components. Manley uses advanced CNC machining to hold incredibly tight tolerances on every valve, ensuring they seal properly and perform consistently. They select specific titanium alloys that offer a great balance of hardness, ductility, and fatigue strength, even at the high temperatures found in the exhaust port. Each valve is put through a rigorous final inspection to make sure it meets Manley's high standards for performance and reliability.

This kit includes a set of 8 exhaust valves, each weighing in at a mere 78 grams. They feature a 1.600-inch head diameter, a 0.3415-inch stem diameter, and an overall length of 5.560 inches. When you're building an engine where every ounce matters for high-RPM capability, these titanium valves are a well-built choice.
