ABSTRACT:
A cylinder head cooling jacket arrangement for an internal combustion engine having a pair of adjacent exhaust ports that extend from the combustion chamber to exhaust port openings formed in the side of the cylinder head. A spark plug well is formed between the exhaust passages and thus provides a vertical wall that precludes the flow of coolant from between the exhaust passages to the opposite side of the cylinder head. Several embodiments of arrangements are provided for insuring a circulating flow of coolant through a cooling jacket formed between the passages and the spark plug well.
