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

Manley Performance has built a solid reputation for making strong engine components, and their Titanium Exhaust Valve Kit is a prime example of that expertise. If you're building a high-performance small block engine for GM, Ford, or Chrysler, these valves are designed to help you get the most out of it, especially when you plan on pushing the engine to higher RPMs.

The big advantage here is the material: titanium. It's significantly lighter than traditional steel valves, which means less mass for your valve springs and camshaft to control. This reduction in weight helps improve engine efficiency and allows the engine to rev more freely and safely to higher speeds. Manley uses a one-piece forged construction with careful grain flow, which makes these valves very durable and avoids potential weak spots found in other designs. They're precisely machined on advanced CNC equipment to ensure they meet very tight tolerances, which is crucial for proper sealing and consistent performance, especially in demanding, high-rpm situations. Manley selects specific titanium alloys that offer a good mix of hardness and ductility, ensuring they can handle the heat and stress of aggressive engine operation.

This kit includes eight exhaust valves, each weighing in at just 68 grams. The head diameter is 1.600 inches, with a 0.3110-inch stem diameter and an overall length of 5.140 inches. Every valve goes through a thorough final inspection to make sure it meets Manley's high standards for reliability and performance. If you're serious about building a high-revving engine, these titanium valves are a well-built choice that can make a notable difference.
