Manley Titanium Exhaust Valve Kit - Small Block - ASCS and Wissota

If you're building a high-performance small block engine for ASCS or Wissota racing, you know how critical reducing internal friction and handling extreme RPMs can be. That's where a set of Manley's Titanium Exhaust Valves comes into play. These aren't just any valves; they're crafted from advanced titanium alloys specifically chosen for their strength, hardness, and ductility at high temperatures, all while being significantly lighter than traditional steel valves. This weight reduction in the valve train means your engine can spin faster and more freely, especially important when you're pushing the limits at high RPMs.

What sets these Manley valves apart is their one-piece forged construction. This method ensures a solid, durable part with consistent grain flow, avoiding the potential weak points found in welded alternatives. They're then meticulously machined on state-of-the-art CNC equipment to exacting tolerances, ensuring a perfect seal and optimal performance every time. Each valve also features a CrN Slick Coating for improved durability and reduced friction, along with inserted hard tips and Manley's unique Bead Loc? keeper groove for secure installation. This attention to detail means you're getting a well-built component ready for demanding applications.

This kit includes eight exhaust valves, each measuring 1.600 inches in head diameter, with a 0.3110-inch stem diameter and an overall length of 5.060 inches. Manley's rigorous quality control process, from material selection to final inspection, ensures you receive a set of valves that meet the highest standards for reliability and performance. When building a race engine where every ounce and every RPM counts, these titanium valves are a solid choice.
