Manley 11964HTB-8 Titanium Intake/Exhaust Valves 2.200" Head Diameter

Manley's titanium valves are manufactured from a premium titanium alloy, delivering the strength and durability needed to withstand extreme cylinder pressures and temperatures while reducing reciprocating valvetrain mass.

These valves are part of Manley's HTB (High Tech Blank) series, which incorporates a precision back-cut design on the valve face to improve airflow dynamics into and out of the combustion chamber. The back-cut geometry promotes smoother flow transitions, helping to maximize volumetric efficiency and power output at high RPM.

Key Features:

• Titanium construction — Significantly lighter than stainless steel valves, reducing valvetrain inertia and allowing higher rev limits
• 2.200" head diameter — Sized for high-flow cylinder head applications
• HTB (High Tech Back-cut) — Precision back-cut valve face for optimized airflow and improved flow coefficients
• High-temperature rated — Engineered to handle extreme combustion temperatures in forced-induction and naturally aspirated race engines
• Precision ground stem — Tight tolerances ensure proper guide fit and long service life

Manley Performance has been a trusted name in professional racing and high-performance engine building for decades. Their titanium valve line is a popular choice among engine builders competing in drag racing, circle track, road racing, and other motorsports disciplines where every gram of weight savings translates to measurable performance gains.
