Pontiac R/F 2.110 Intake Valves

The Pontiac R/F 2.110 Intake Valves by Manley represent purpose-built race-series components engineered for serious V8 builders and performance enthusiasts. These stainless steel intake valves are designed for Pontiac V8 engines that demand reliability under extreme combustion pressures and sustained high RPM operation. Whether you're building a competition engine, restoring a classic muscle car, or upgrading an existing platform, these valves deliver the precision fit and durability required for demanding applications where factory components fall short.

Each valve features a 2.110-inch head diameter paired with a 0.342-inch valve stem, optimized for flow characteristics and seat engagement in race-prepared cylinder heads. The 5.215-inch overall length ensures proper clearance within your engine's valve train geometry while maintaining the precise dimensions required for tight concentricity and minimal wobble during operation. Manufactured from stainless steel, these valves resist corrosion, thermal stress, and the chemical assault of modern fuel blends while maintaining superior heat conductivity compared to conventional intake valves. The complete set of eight valves (one per cylinder) arrives ready for installation, though proper valve seat machining and clearance verification are essential before assembly.

These intake valves suit Pontiac V8 engine builders, vintage race car restorers, and performance shops tackling comprehensive top-end rebuilds. Compatibility with your specific engine requires verification of valve seat pocket dimensions and pushrod clearances—professional installation or guidance from an experienced machine shop is strongly recommended. The set weighs 2.52 pounds total, reflecting the density of high-grade stainless construction. Pair these valves with matched exhaust valves, quality springs, retainers, and locks to ensure a harmonized, reliable valve train capable of sustained competition service.
