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

Starting with titanium construction, these Manley exhaust valves are built for serious performance. Titanium is significantly lighter than traditional steel, and that weight reduction in the valve train makes a big difference, especially when you're pushing your engine to higher RPMs. If you're building a performance engine for a Small Block GM, Ford, or Chrysler that's going to see a lot of time at high revs, these valves are designed to handle it.

Manley forges these valves from a single piece of titanium, which creates a stronger part with better grain flow compared to valves that are welded together. They're then machined on advanced CNC equipment to very precise measurements, ensuring they seal perfectly and operate smoothly. The specific titanium alloys Manley uses are chosen for their strength, hardness, and ability to hold up under high temperatures and stress, giving you a durable part that's ready for demanding use. The 'HT' designation means they use high-temperature material, and they even have hard tips inserted for added durability.

This kit includes eight exhaust valves, each weighing in at just 79 grams. The head diameter is 1.625 inches, the stem is 0.3415 inches, and the overall length is 5.460 inches. Manley puts these through a strict final inspection to make sure they meet their high standards for quality and reliability, so you can be confident in their performance.
