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 RPMs, you'll want to take a serious look at this Manley Titanium Exhaust Valve Kit. These aren't your average valves; they're crafted from exceptional 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. Less weight means the engine can spin faster and more freely, which is crucial for aggressive camshaft profiles and extended high-RPM operation. You'll notice improved engine efficiency and overall performance when you're really asking your engine to work.

Manley builds these valves using a one-piece forged construction process. This method ensures a solid, durable part with consistent grain flow, avoiding the potential weak points found in head-welded alternatives. They're then meticulously machined on advanced CNC equipment, including specialized valve stem grinders, to hold incredibly tight tolerances. This precision machining is key to ensuring optimal valve performance and sealing. The 'HT' suffix on these valves indicates they are made from high-temperature material, and they also feature inserted hard tips for added durability in demanding conditions.

This kit includes eight exhaust valves, each weighing in at a mere 83 grams, with a head diameter of 1.625 inches and a stem diameter of 0.3415 inches. Each valve is put through a rigorous final inspection to guarantee uncompromising quality and reliability. When you're building an engine for serious performance, using components like these titanium valves can make a notable difference in how the engine performs and handles stress.
