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 rev higher and more freely, especially when paired with aggressive camshaft profiles. This reduction in mass helps prevent valve float and improves overall engine efficiency under demanding conditions.

What sets these valves apart is their one-piece forged construction. This method ensures a solid, durable part with superior grain flow compared to valves that are welded at the head, minimizing potential failure points. Manley uses specific titanium alloys chosen for their balance of hardness, ductility, and fatigue strength at the high temperatures exhaust valves endure. They're then meticulously machined in advanced CNC centers to exacting tolerances, ensuring a precise fit and optimal sealing. Each set undergoes rigorous final inspection to guarantee uncompromising quality and reliability, delivered within tight tolerances for your build.

This kit includes a set of 8 exhaust valves, each weighing in at a mere 75 grams. The head diameter measures 1.600 inches, with a stem diameter of 0.3415 inches and an overall length of 5.260 inches. These valves are a substantial upgrade for any performance-oriented engine build where reducing reciprocating mass and handling high engine speeds are key objectives.
