Abstract
A unitary cylinder head casting for an engine includes a plurality of valve guide bore casting portions, each valve guide bore casting portion defining a valve guide bore and a plurality of head bolt bore casting portions, each head bolt bore casting portion defining a head bolt bore. The cylinder head casting is constructed and arranged such that there is at least one head bolt bore corresponding to each valve guide bore. The cylinder head casting also defines an upper water jacket and a lower water jacket. In order to eliminate fillets in the area of the upper water jacket which represent likely locations for fatigue cracks to initiate, gusset ribs are included as part of the cylinder head casting. There is at least one gusset rib extending between at least one combination of one head bolt bore casting portion and its corresponding valve guide bore casting portion.
