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

When you're building a high-performance engine, especially one that's going to see a lot of time at higher RPMs, every ounce counts. This kit from Manley Performance includes eight titanium exhaust valves, specifically designed for Small Block GM, Ford, and Chrysler applications. Titanium is significantly lighter than traditional steel, which helps reduce the overall weight of your valve train. This means less stress on your components and the potential to rev the engine higher and more reliably.

Manley makes these valves using a one-piece forged construction, which is a strong method that ensures the grain flows properly through the part, minimizing potential weak spots. They're then precisely machined on advanced CNC equipment to very tight tolerances, ensuring they seal well and perform consistently. The titanium alloys used are chosen for their balance of strength, hardness, and ductility, especially at the high temperatures found in an exhaust valve. The 'HT' in the part number means they're made from high-temperature material, and they also feature inserted hard tips for added durability where the rocker arm makes contact.

This set includes eight exhaust valves, each measuring 1.625 inches across the head and having a 0.3415-inch stem diameter. They have an overall length of 5.460 inches and weigh about 85 grams each. Because these are specialized performance parts, it's always a good idea to consult your engine builder or the manufacturer's instructions for specific installation details and compatibility with your camshaft and valvetrain setup.
