ABSTRACT:
A cylinder head has a cylinder head body, a camshaft housing mounted on the cylinder head body, and cam caps mounted on the camshaft housing. The camshaft housing has through holes into which bolts are inserted to secure the camshaft housing and the cam caps together to the cylinder head body when assembling the engine. Internal threads are formed on the inner surfaces of the through hole, respectively. When rounding the cam holes before assembling the engine, second bolts are temporarily tightened to the internal threads of the through holes to secure the cam caps to the cam housing.
