The 1.880 BBC Exhaust Valve (part number BR 82138) is a precision-engineered stainless steel exhaust valve designed specifically for big block Chevy engines. With an 11/32-inch valve stem and 5.494-inch overall length, this exhaust valve delivers the dimensional accuracy required for reliable combustion chamber sealing and optimal engine performance in high-displacement Chevy big block applications.
Stainless steel construction provides superior corrosion and heat resistance compared to standard steel valves, extending component life in demanding engine conditions. The 1.880-inch head diameter seats precisely within big block Chevy cylinder head specifications, while the 11/32-inch stem diameter ensures proper valve guide fitment and consistent operation across intake and exhaust cycles.
This exhaust valve is essential for engine rebuilds, restorations, and performance upgrades on big block Chevy platforms including 427, 454, and 502 cubic-inch variants. Whether completing a full cylinder head reconditioning or replacing worn exhaust valves, users benefit from the proven durability and precise fitment of factory-specification components.
