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

If you're rebuilding the top end of a small block GM, Ford, or Chrysler engine 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 periods at high engine speeds, where reducing reciprocating mass becomes critical for reliability and performance.

What sets these valves apart is their construction. They're forged from a single piece of high-grade titanium alloy, which is significantly lighter than traditional steel valves. This one-piece forging process, with careful attention to grain flow, creates a stronger, more durable valve compared to those made with welded components. Manley then machines them to very tight tolerances using advanced CNC equipment, ensuring they seal properly and perform consistently. The specific titanium alloy chosen offers a good balance of hardness for durability and ductility for strength, even at the elevated temperatures found in the exhaust port.

This kit includes eight exhaust valves, each weighing in at a mere 78 grams. They feature a 1.625-inch head diameter and a 0.3415-inch stem diameter, with an overall length of 5.460 inches. The precise machining and strict quality control mean you're getting valves that meet exacting standards, which is crucial for proper engine function and longevity when you're running your engine hard. Proper installation is key, so be sure to refer to the manufacturer's instructions for details on fitting these into your cylinder heads.
