32mm Replacement Exhaust Valve – For Wildcat 460 & Big Block Clone Engines

Maintain exhaust flow and engine reliability with this stock replacement 32mm exhaust valve, designed for the Wildcat 460 and other compatible big block clone engines. Precision-machined from carbon steel, this valve is built to withstand high combustion temperatures while delivering consistent performance in both stock and performance engine builds.

Featuring a 1.260" (32mm) head diameter and 6.5mm (.256") valve stem, this exhaust valve fits Wildcat 460 cylinder heads and similar platforms.
