BBC S/D 1.850 Exhaust Valves

The BBC S/D 1.850 Exhaust Valves are specifically designed for high-performance marine Big Block Chevy engines, providing the durability needed for extreme thermal loads and high-RPM stress. These valves are ideal for boaters who push their offshore setups to the limit, ensuring reliability during extended runs in challenging conditions.

Constructed from durable stainless steel, these valves feature a 1.850-inch head diameter and a precision-ground 0.342-inch valve stem. Their 5.500-inch overall length is optimized for proper valvetrain geometry, promoting effective heat dissipation across the valve face. The severe-duty designation signifies their ability to withstand the harsh conditions often encountered in marine environments.

These valves are particularly beneficial for owners of Brodix BB383 heads seeking a reliable valvetrain solution for their marine engine builds or seasonal refreshes. Sold as a complete set of 8, they ensure uniform performance across all cylinders in high-displacement Big Block Chevy applications.
