Manley 11940HB-8 Titanium Intake Valves 2.325" Head Diameter +.250" Over Stock Height

Featuring a 2.325" head diameter, 0.3415" stem diameter, and a square keeper groove, these valves are built +0.250" longer than stock overall height — making them ideal for use with raised deck blocks or custom valvetrain geometry requiring additional installed height.

Constructed from premium titanium alloy using a forged one-piece design with grain flow, these valves deliver an exceptional strength-to-weight ratio without the potential weak points of a head-welded-to-stem construction. Each valve is micro-polished to a jewel-like surface finish that eliminates stress risers and maximizes fatigue strength. The result is a valve that significantly reduces valvetrain mass, enabling quicker valve action, higher RPM capability, and improved throttle response.

Key Features:

• Titanium alloy construction — significant weight savings over stainless steel
• 2.325" head diameter
• 0.3415" stem diameter
• +0.250" longer than stock overall height (HB = Higher Base / extended height)
• Square keeper groove style
• Forged one-piece construction with grain flow — no welded head-to-stem joint
• Micro-polished finish eliminates stress risers and increases fatigue strength
• CNC-machined to exacting tolerances in state-of-the-art turning centers
• Rigorous final inspection for consistent quality and tight tolerance delivery
• Special order / non-stock item — non-returnable

Manley Performance titanium valves are the preferred choice for drag racing, road racing, and high-performance street engines where valvetrain weight reduction and high-RPM durability are critical. Verify guide clearances before installation, as Manley stem sizes may differ from nominal guide dimensions on some aftermarket cylinder heads.
