Abstract
A unitary cylinder head assembly for a five-valve per cylinder internal combustion engine. The cylinder head assembly has upstanding walls that form tappet receiving bores for receiving the tappets that operate the respective valves. In addition, these walls provide bearing surfaces for a pair of camshafts, one of which actuates one set of valves and the other of which actuates another set of valves. The threaded fastening means for affixing the cylinder head to the cylinder block are disposed axially beyond the walls and in the case of the set containing the greater number of valves transversely outwardly from the walls. However, the threaded fastening means are disposed so that they are equal distance from the associated cylinder bore axis.
