ABSTRACT:
An arrangement for rotatably supporting first and second camshafts associated with first and second series of plural valves for the combustion chamber of an internal combustion engine. A cylinder head is affixed to the cylinder block by fastening means that are equally spaced with respect to the cylinder bores while the camshafts are offset at different distances from the cylinder bore axis on opposite sides of the cylinder head. The fastening arrangement includes cam carriers and bearing caps that support the respective camshafts and which are spaced so as to avoid interference with each other and to provide uniform tightening loads.
