BBM R/F 1.810in Exhaust Valves

The Manley BBM R/F 1.810in Exhaust Valves are precision-engineered components designed for high-performance engine builders and automotive enthusiasts. These valves are essential for maximizing flow efficiency and durability in modified or racing applications, particularly in builds targeting increased power output and extended engine longevity.

Constructed with Manley's proprietary materials and advanced heat-treatment processes, the BBM R/F (Reverse Flow) design optimizes exhaust gas evacuation while minimizing turbulence and backpressure. The 1.810-inch head diameter provides a balance between flow capacity and seating geometry, allowing for larger valve lift without compromising reliability.

These valves are ideally suited for racers and performance shops working on competition platforms, particularly LS-family engines. Installation requires proper valve seat profiling and compatibility verification with specific cylinder head castings, ensuring optimal performance in high-stress environments.
