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

If you're building a high-performance small block engine for GM, Ford, or Chrysler, you'll want to take a look at this Manley Titanium Exhaust Valve Kit. These aren't your average valves; they're made from special titanium alloys chosen for their strength and light weight, which is crucial when you're pushing your engine to higher RPMs. Reducing the weight in the valve train means the engine can spin faster and more freely, especially important for racing or aggressive camshaft profiles.

What really sets these apart is the one-piece forged construction. This method ensures the grain flows properly through the valve, making it incredibly strong and less likely to fail compared to valves that are welded together. Manley machines these valves with very precise tolerances using advanced CNC equipment, so you know they'll seal and perform exactly as they should. The titanium alloy used is specifically selected to handle the heat and stress of demanding engine use, balancing hardness with ductility for long-term reliability. The 'HT' in the part number means it's made with high-temperature material, and they even have inserted hard tips to handle the impact from the valvetrain.

This kit includes a set of 8 exhaust valves, each weighing only 86 grams, with a head diameter of 1.625 inches and a 0.3415-inch stem diameter. Manley puts each valve through a thorough final inspection to make sure they meet their high standards for quality and performance. When you're building an engine where every ounce and every RPM counts, these titanium valves are a solid choice to help you achieve your goals.
