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 of weight savings counts. This kit from Manley Performance gives you eight titanium exhaust valves, specifically made for small block GM, Ford, and Chrysler engines. Titanium is significantly lighter than traditional steel, which helps reduce the overall stress on your valve train. This means your engine can spin faster and more reliably, especially when paired with aggressive camshafts.

Manley makes these valves from a single piece of forged titanium, which is a strong construction method that avoids potential weak spots you might find in welded designs. They're machined with very tight tolerances on advanced CNC equipment, ensuring each valve seals perfectly and operates smoothly. The specific titanium alloys Manley uses are chosen for their balance of strength, hardness, and ductility, so they can handle the heat and stress of demanding engine use. Each valve is thoroughly inspected to make sure it meets Manley's high standards for performance and durability.

This set includes eight exhaust valves, each with a 1.600-inch head diameter and a 0.3415-inch stem diameter, with an overall length of 5.140 inches. They weigh in at about 74 grams each. These are designed for serious engine builds where reducing mass and handling high RPMs are critical goals.
