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 high RPMs, every ounce counts. This kit from Manley Performance includes eight titanium exhaust valves, specifically made for Small Block GM, Ford, and Chrysler engines. Titanium is significantly lighter than traditional steel valves, which means less mass for your valve springs to control. This helps prevent valve float at high engine speeds and allows your engine to rev more freely.

Manley makes these valves from a single piece of forged titanium, which is a strong way to build them, avoiding potential issues that can come with welding. They're machined precisely on advanced CNC equipment to ensure they meet very tight tolerances, which is crucial for a good seal and consistent performance. The specific titanium alloys Manley uses are chosen for their balance of strength, hardness, and ductility, making them durable even at the high temperatures found in exhaust ports. Each valve is checked thoroughly to make sure it meets Manley's high standards before it ships out.

This set includes eight exhaust valves, each with a 1.600-inch head diameter and a 0.3415-inch stem diameter, measuring 5.360 inches overall. They weigh in at about 78 grams each, which is a notable reduction compared to steel. If you're aiming for maximum engine speed and efficiency in your build, these titanium valves are a solid choice.
