1. An internal combustion engine comprising:
a base;
a cylinder block mounted onto the base;
a cylinder head mounted onto the block;
a structural overhead member removably mounted onto the cylinder head such that the cylinder head is positioned between the cylinder block and the structural overhead member, the structural overhead member defining apertures configured to receive and retain intake and exhaust cam shafts in a spaced apart relationship with the cylinder head; and
at least one through-bolt positioned in a through-bolt opening, the through-bolt opening extending from the base to the structural overhead member through the cylinder block and the cylinder head to couple the base, the cylinder block, the cylinder head and the structural overhead member together.
