Manley Titanium Exhaust Valve Kit - Small Block Chevrolet - GB 2300

If you're rebuilding the top end of your Small Block Chevrolet and pushing the limits with high-RPM operation, these Manley Titanium Exhaust Valves are a serious consideration. They're built to handle the demands of aggressive camshafts and extended high-rpm use, helping your engine breathe better when it's spinning fast.

What sets these apart is the material. Manley uses special titanium alloys that are not only lightweight but also incredibly durable, offering a great balance of hardness and ductility even at high temperatures, as indicated by the 'HT' in the part number. This isn't just a simple titanium coating; these are one-piece forged valves with advanced grain flow, meaning they're strong and minimize potential failure points. They're machined to very tight tolerances on CNC equipment, ensuring each valve seals perfectly and performs consistently. The weight savings alone can make a notable difference in valve train stability at higher engine speeds.

This kit includes eight exhaust valves, each weighing around 85 grams, with a 1.600-inch head diameter and a 0.3415-inch stem diameter. They also feature inserted hard tips and Manley's Bead Loc single radius keeper groove for secure installation. When you're aiming for maximum performance and reliability in a high-revving engine, these valves are a well-built choice.
