Manley 11710H-8 2.055" Hollow Stem Sodium-Filled Intake Valves +.200" Length

Designed for demanding performance and racing applications, these valves deliver exceptional heat dissipation and durability far beyond standard OEM replacements.

Manley's hollow stem sodium-dampened design allows heat to transfer rapidly away from the valve head and into the valve guide, significantly reducing operating temperatures and extending valve life under extreme conditions. The extra 0.200-inch length accommodates performance cylinder head porting work and allows for proper geometry correction when using aftermarket valve train components.

Key Features:

• 2.055" head diameter — a common performance intake valve size for small block and big block applications
• Hollow stem, sodium-filled construction for superior thermal management and heat transfer
• +0.200" over-stock length to accommodate ported cylinder heads and corrected rocker arm geometry
• Manufactured by Manley Performance, a trusted name in professional racing and high-performance engine building
• Precision-machined to tight tolerances for consistent sealing and long service life

Manley Performance has been producing championship-winning engine components since 1947. The 11710H-8 valves are ideal for engine builders seeking a reliable, race-proven intake valve solution with enhanced heat dissipation for forced induction, high-RPM, or high-compression builds.
