ABSTRACT:
An internal combustion engine has cylinder head assembly. First and second cams are disposed on a camshaft for rotation therewith. A first cam follower has a first end journaled on a cam follower shaft and a second end abutting an end of a first valve. A second cam follower has a first end journaled on the cam follower shaft and a second end abutting an end of a second valve. A spacer is disposed at least partially around the cam follower shaft. The spacer is disposed between the cam followers such that the first cam follower is disposed between the spacer and a camshaft support and the second cam follower is disposed between the spacer and another camshaft support. A cylinder head assembly, a method of accessing the valves, and embodiments providing for the supply of lubricant to the cam followers are also disclosed.
