BBM C/6 2.190in Intake Valves

The BBM C/6 2.190-inch intake valves (Part No. F6189-8) are premium stainless-steel valve assemblies engineered for big-block engine platforms including Chevrolet, Mopar, Ford, and Cleveland blocks. This set of eight intake valves features a 2.190-inch head diameter paired with an 11/32-inch valve stem and extends 5.344 inches in length, delivering the precise dimensions required for high-flow intake porting and reliable combustion chamber sealing across a broad range of displacement and compression scenarios.

Stainless-steel construction provides superior corrosion resistance and thermal stability compared to conventional chrome-plated alternatives, a critical advantage in high-heat environments where valve recession and stem wear can compromise engine longevity. The 2.190-inch head diameter is optimized for big-block cylinder heads designed to that specification, ensuring proper seat contact area and sealing integrity under sustained load. The 11/32-inch stem diameter maintains compatibility with standard valve guides and rocker assemblies across these engine families, eliminating fitment complications during installation and teardown.

This valve set addresses the needs of engine builders, restoration specialists, and performance enthusiasts working with classic and contemporary big-block platforms. Whether performing a stock rebuild, porting-and-polishing a cylinder head, or assembling a high-compression stroker motor, having a matched set of eight intake valves in stainless steel ensures consistent flow characteristics and eliminates the risk of mixing material compositions across the intake valve bank. The specification supports applications ranging from street engines to track-oriented builds where thermal cycling and sustained RPM stress demand reliable metallurgy.
