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 Valve Kit is a prime example of that dedication. If you're working on a Small Block GM, Ford, or Chrysler engine and pushing the limits with high-RPM operation, these valves are designed to handle the stress and help your engine breathe better.

The key advantage here is the use of titanium. It's significantly lighter than traditional steel valves, which means less mass moving around in your valve train. This reduction in weight not only improves overall engine efficiency but also allows your engine to rev higher and more reliably, especially in demanding high-RPM applications. Manley constructs these valves from a single piece of forged titanium, which is a strong method that avoids potential weak points found in welded designs. They're then precisely machined on advanced CNC equipment to exacting tolerances, ensuring they seal perfectly and perform consistently.

Manley selects specific titanium alloys that offer a great balance of hardness, ductility, and fatigue strength, crucial for valves that operate under high temperatures and stress. Each valve goes through a thorough final inspection to make sure it meets Manley's high standards for quality and reliability. This kit includes eight exhaust valves, each measuring 1.625 inches in head diameter, 0.3415 inches in stem diameter, and 5.460 inches in overall length, with each valve weighing in at a mere 78 grams.
