Manley Titanium Exhaust Valve Kit - Big Block General Motors

Manley Performance has built a solid reputation for making well-built engine components, and their Titanium Exhaust Valves are a prime example of that commitment. If you're working on a Big Block General Motors engine and pushing the limits with high-RPM operation, these valves are designed to handle the stress. They're crafted from exceptional titanium alloys, chosen specifically for their balance of strength, hardness, and ductility at the high temperatures found in performance engines.

What really sets these valves apart is their one-piece forged construction. This method, combined with careful grain flow management, creates a stronger, more durable valve compared to designs that use welding. Manley machines these valves with tight tolerances using advanced CNC equipment, ensuring they perform precisely as they should. The titanium material itself is key to reducing overall valve train weight, which helps the engine rev faster and more freely, especially in demanding, extended high-RPM situations. This kit includes 8 exhaust valves, each with a 1.900-inch head diameter and a 0.3415-inch stem diameter, and features Manley's Bead Loc groove.

For engines running aggressive camshaft profiles or consistently operating at high speeds, these titanium valves are a smart choice. It's important to note that while these are exhaust valves, Manley also offers titanium intake valves. For part numbers without a 'T' suffix, tip protection is required; Manley wear cap part numbers 42104 or 42104TM are recommended for this purpose.
