Description

OEM 5mm Stem 25mm Exhaust Valve for Wildcat 223 Hemi Engines


The OEM 25mm Exhaust Valve is the factory-standard exhaust valve used in the Wildcat 223 Hemi engine. This valve features a 5mm stem and is designed specifically for Wildcat’s Hemi-style cylinder heads, utilizing automotive-style 5mm retainers and valve locks included in the original head assembly.


While other engines—such as the Tillotson 212R/225 and Predator 212 Non-Hemi—also use 5mm valve guides, this valve is 0.345” longer than those applications and is not cross-compatible.
