BBC R/M 2.190in Intake Valve

The Manley BBC R/M 2.190in Intake Valve is a race-proven component engineered for serious big-block engine builders and performance enthusiasts. Designed specifically for big-block Chevy, Ford, and Cleveland platforms, this intake valve delivers the precision geometry and material science required for high-RPM applications where stock valves simply cannot survive thermal and mechanical stress. Whether you're building a competition engine, restoring a classic muscle car, or maximizing power output on an existing platform, this race master valve provides the durability and flow characteristics necessary to unlock your engine's full potential.

Manufactured from premium stainless steel, the BBC R/M 2.190in Intake Valve features a 2.190-inch head diameter with a 0.342-inch valve stem and measures 5.244 inches in overall length. The stainless construction provides superior corrosion resistance, higher melting point stability, and improved durability compared to conventional iron valves—critical factors when operating at elevated temperatures and boost pressures common in modified engines. The 2.190-inch head size is optimized for cylinder head ports designed to accept race-specification intake valves, offering superior flow dynamics and seat contact that minimize turbulence and maximize volumetric efficiency throughout the RPM band.

This valve serves professional engine builders, weekend warriors, and competitive racers who demand reliability without compromise. Installation requires proper seat and guide sizing to match the 0.342-inch stem diameter—precision machine work that should only be entrusted to experienced builders familiar with race motor assembly. The BBC R/M 2.190in Intake Valve is sold individually, so you'll need multiple valves depending on your cylinder count; always verify compatibility with your specific head casting before ordering. For maximum performance gains, pair this valve with a properly matched exhaust valve, quality valve springs, and a flow-tested cylinder head package.
