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

Manley's titanium exhaust valves start with a one-piece forged construction, a design choice that ensures solid durability by minimizing potential weak points often found in head-welded alternatives. These valves are meticulously machined in advanced CNC turning centers, holding exacting tolerances that are crucial for optimal valve performance, especially when you're pushing your engine to higher speeds. The specific titanium alloys Manley uses strike a careful balance between mechanical strength, hardness, ductility, and fatigue resistance at the elevated temperatures found in performance engines.

The primary advantage here is significant weight reduction. Each exhaust valve weighs in at just 79 grams, with a 1.600-inch head diameter and a 5.460-inch overall length. This reduced mass in the valve train is key for improving engine efficiency and allowing for higher, more sustained engine speeds. They are specifically suited for high-rpm applications and can handle aggressive camshaft profiles, making them a solid choice for serious engine builds where every gram counts and reliability at speed is paramount.

Manley puts these titanium valves through a rigorous final inspection process to ensure uncompromising quality and performance. This strict quality control means you're getting valves delivered within tight tolerances, meeting the highest precision standards for your engine build. This kit includes a set of 8 valves, ready to be installed in your Small Block GM, Ford, or Chrysler engine.
