Manley Titanium Exhaust Valve Kit - Small Block Chevrolet - All Pro

If you're building a high-performance Small Block Chevrolet engine designed to spin fast and hard, you'll want to pay close attention to valve train weight. These Manley Titanium Exhaust Valves are specifically made to cut down on that rotating mass, which helps your engine breathe better and rev more freely. They're a popular choice for serious engine builds where every ounce counts and the engine will be pushed to its limits.

Manley starts with exceptional titanium alloys, chosen for their balance of strength, hardness, and ductility at high temperatures. They then forge these valves into a single piece, which is a stronger design than those that weld the tip on. This one-piece construction, combined with advanced CNC machining to very tight tolerances, ensures each valve performs consistently and reliably. The 'HT' in the part number means these are made from high-temperature material, perfect for exhaust duty where things get really hot. You'll also find they come with inserted hard tips and Manley's Bead Loc keeper groove, which helps secure the valve spring retainer.

This kit includes a set of 8 exhaust valves, each weighing in at just 77 grams, with a 1.600-inch head diameter and a 5.950-inch overall length. Because these are specialized performance parts, it's always a good idea to consult your engine builder or refer to Manley's installation guidelines to ensure they integrate perfectly with your specific camshaft and cylinder head setup.
