Abstract
An internal combustion engine has a cylinder head defining an exhaust valve guide bore with a side wall and an end wall, and an exhaust valve stem passage extending between an exhaust port and the end wall of the bore. A diameter of the passage is less than a diameter of the bore. An exhaust gas valve guide is positioned in the bore and spaced apart from the end wall to form an air gap therebetween.
