Pontiac R/M 2.110in Intake Valves

The MANLEY Pontiac R/M 2.110in Intake Valves are a set of eight race-series intake valves engineered for high-performance Pontiac V8 engines. Built from stainless steel, these valves deliver the precision flow characteristics and durability required for sustained high-RPM operation. With a 2.110-inch head diameter and 0.342-inch valve stem, they're designed to maximize intake charge velocity while maintaining structural integrity under aggressive valve spring pressures typical of performance and racing applications.

Each valve measures 5.100 inches in total length and is manufactured to exacting tolerances critical for repeatable seating and minimal valve guide wear. The stainless construction resists corrosion and heat-related degradation, ensuring consistent performance across extended dyno runs or track sessions. The race-series designation indicates these valves are optimized for applications where stock OEM tolerances are insufficient—whether for naturally aspirated high-compression builds or forced-induction setups where cylinder head flow becomes the limiting factor. Proper installation requires precision honing of valve seats and guides to factory specifications.

This eight-valve set is intended for engine builders, performance shops, and serious Pontiac V8 enthusiasts pursuing maximum intake efficiency. Whether rebuilding a ported and polished head or upgrading an existing engine package, these MANLEY intake valves serve as a proven foundation for repeatability and reliability at competition power levels. The set covers all intake positions in a Pontiac V8 configuration, eliminating the need for partial purchases or mixed-vintage components.

MANLEY has established itself as a trusted OEM and aftermarket supplier of precision valvetrain components for decades, with proven track record in both street and racing applications. For builders seeking verified performance components backed by manufacturing expertise, MANLEY race-series valves represent the mid-tier option between basic restoration parts and ultra-premium lightweight titanium alternatives.
