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, then these Manley Titanium Exhaust Valves are worth a serious look. These aren't your everyday valves; they're crafted from advanced titanium alloys specifically chosen for their balance of strength, hardness, and ductility at high temperatures. The primary advantage here is significant weight reduction in the valve train, which directly translates to improved engine efficiency and the ability to safely achieve higher engine speeds. This makes them a popular choice when building engines for racing or other demanding applications where every ounce and every RPM counts.

Manley builds these valves using a one-piece forged construction process. This method ensures a solid, durable part with excellent grain flow, avoiding potential weak points that can occur with head-welded designs. They are then meticulously machined on state-of-the-art CNC equipment, including specialized valve stem grinders, to hold extremely tight tolerances. This precision machining is critical for ensuring a proper seal and optimal performance within the cylinder head. The titanium alloys used are selected for their durability and fatigue strength, meaning they're built to withstand the rigors of extended high-RPM use without premature failure. Each valve goes through a strict final inspection to guarantee uncompromising quality and reliability.

This kit includes a set of eight exhaust valves, each weighing in at a mere 73 grams. They feature a 1.600-inch head diameter, a 0.3415-inch stem diameter, and an overall length of 5.140 inches. The stem has a groove for the locators. When you're aiming for peak performance and need a valve train that can keep up with aggressive camshaft profiles and sustained high engine speeds, these Manley titanium valves offer a well-built solution.
