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

If you're rebuilding the top end of your 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 helps your engine spin faster and more freely, especially under demanding conditions. This reduction in mass also means less stress on your camshafts and other valvetrain components.

What sets these valves apart is their one-piece forged construction. Unlike some other designs that might use welding, Manley forges these valves from a single piece of high-strength titanium alloy. This process ensures a solid, durable part with consistent grain flow, minimizing potential failure points. They're then meticulously machined on advanced CNC equipment to very tight tolerances, ensuring they seal properly and perform reliably. The titanium alloy used is chosen specifically for its balance of hardness, ductility, and fatigue strength at the high temperatures exhaust valves encounter.

This kit includes a set of eight valves, each weighing in at a mere 86 grams, with a head diameter of 1.625 inches and a 0.3415-inch stem diameter. The 'HT' designation means they use a high-temperature material, and they also feature inserted hard tips to handle the impact of valve seating. When you're aiming for maximum performance and reliability in a high-revving engine, these well-built titanium valves are a solid choice.
