Exhaust Valve - 1.810 (1)

The Exhaust Valve - 1.810 in Head by Edelbrock is a precision-engineered intake and exhaust valve assembly designed for serious engine builders and performance enthusiasts working with Mopar B and RB-series engines. This stainless steel exhaust valve is engineered to handle the extreme temperatures and pressures found in high-performance combustion chambers, making it an essential upgrade for anyone seeking to maximize engine efficiency, durability, and reliability in their Edelbrock Performer RPM 440 build.

Manufactured from premium stainless steel, this exhaust valve features a 1.810-inch head diameter and 11/32-inch valve stem, specifications that ensure optimal sealing and heat dissipation under demanding operating conditions. The valve stem geometry is precisely sized to match Mopar B and RB-series cylinder head port specifications, providing exact fitment and consistent valve train performance. Stainless steel construction provides superior corrosion resistance and thermal stability compared to standard steel valves, extending service life and maintaining precise clearances across varying engine temperatures and RPM ranges.

Engine builders and restoration specialists rely on Edelbrock exhaust valves when rebuilding or upgrading classic and performance Mopar engines, particularly in 440 cubic-inch displacement applications where valve durability directly impacts peak horsepower and engine longevity. Installation requires proper valve seat preparation and clearance verification; this single valve is sold individually, allowing builders to replace worn or damaged units or purchase matched sets for complete cylinder head refreshes. Compatible with Edelbrock Performer RPM 440 cylinder head packages and original Mopar B and RB-series applications, this valve ensures precise valve timing and chamber sealing for maximum combustion efficiency.
