Part Description
Valve EX Blank 1.7"x5.7"
Text excerpt from the catalog:
These high-flow blank stem valves are great for engine builders that really want to go that extra mile to squeeze the last horsepower and foot-pound from an engine. Stems are blank, key grooves must be machined by a professional. Valves must be used with valve stem lash caps as the valve stem tip comes unhardened. Stems are centerless ground to a micro finish with a hard chrome finish for a longer life.
