Inconel exhaust valves offer far superior reliability to OEM style stainless sodium filled exhaust valves which often crumble into the cylinder. Inconel alloy material is a large upgrade over traditional stainless steel valves due to its extremely high heat resistance.
Highly recommended for use as exhaust valves in engines that reach very high temperatures such as turbocharged and supercharged applications.
** Also Available in Single Groove style. Keepers will be required for those - contact for availability
