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

This kit includes eight Manley Titanium Exhaust Valves, specifically made for Small Block GM, Ford, and Chrysler engines. These valves are a smart choice when you're looking to get the most out of your engine, especially if you plan on running at higher engine speeds or using aggressive camshafts. The titanium construction is key here, as it significantly cuts down on valve train weight. Less weight means the valvetrain can keep up better at high RPMs, reducing the chance of valve float and allowing your engine to rev more freely.

Manley builds these valves from a single piece of forged titanium, which is a strong way to make them. This method ensures the grain flow is correct throughout the valve, making it more durable than valves that are welded together. They're then precisely machined on advanced CNC equipment to very tight tolerances, ensuring they seal well and perform consistently. Manley selects specific titanium alloys that offer a good mix of hardness for durability, ductility for toughness, and fatigue strength, especially important when the engine is running hot and fast. Each valve is checked thoroughly before it leaves the factory to make sure it meets their high standards for quality and reliability.

With a 1.600-inch head diameter and a 0.3415-inch stem diameter, these valves are designed for optimal flow and compatibility with many popular Small Block cylinder heads. The overall length is 5.360 inches, and they weigh in at a light 76 grams each, further contributing to that reduced valvetrain mass. This kit is a solid option for anyone building a performance engine where high-RPM capability and reduced internal friction are important goals.
