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

Manley Performance is well-known for making strong engine components, and this Titanium Exhaust Valve Kit for Small Block engines is a prime example of their work. If you're building a high-performance small block for demanding applications like ASCS or Wissota racing, reducing weight in the valve train is key to handling higher engine speeds and improving overall efficiency. These valves are designed to do just that.

What sets these valves apart is their one-piece forged construction. This method, combined with careful grain flow management, makes them incredibly durable and avoids potential weak spots you might find in other designs. Manley uses exceptional titanium alloys, chosen specifically for their balance of hardness, ductility, and fatigue strength at the high temperatures these valves will see. They're then meticulously machined in advanced CNC centers to very tight tolerances, ensuring they perform exactly as they should. The valves also come with a CrN Slick Coating for durability and have inserted hard tips, plus Manley's unique Bead Loc? single radius keeper groove.

This kit includes a set of 8 exhaust valves, each weighing in at just 74 grams with a 1.600-inch head diameter and a 0.3415-inch stem diameter. The overall length is 5.160 inches. Because these are such critical components for high-rpm use, Manley puts them through a rigorous final inspection to make sure every valve meets their high standards for performance and reliability.
