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

What you're getting here is a set of eight Manley Titanium Exhaust Valves, specifically made for Small Block GM, Ford, and Chrysler engines. These aren't your everyday valves; they're crafted from top-grade titanium alloys to significantly cut down on valve train weight. This reduction is crucial for engines that need to spin up fast and stay there, especially when you're running aggressive camshafts or pushing for higher engine speeds.

Manley builds these valves as a single forged piece, which means the grain flows through the entire component, making them incredibly strong and less prone to failure than valves that are welded at the head. They're then precisely machined on advanced CNC equipment to ensure they meet very tight tolerances, which is key for proper sealing and efficient engine operation. The titanium alloy itself is chosen for a good mix of strength, hardness, and the ability to handle the heat and stress of high-RPM use without fatiguing over time. Each valve is put through a strict final inspection to make sure you're getting a reliable part that performs exactly as it should.

With a head diameter of 1.625 inches and a stem diameter of 0.3415 inches, these valves are designed for specific applications where reducing mass is the priority. Each valve weighs in at a light 75 grams, contributing to an overall improved engine response and efficiency, particularly in demanding, high-RPM scenarios.
