    摘要: A liquid cooled cylinder head (30a) for an internal combustion engine (10) is cast without internal liquid coolant passages to interconnect first and second cooling cavities (80 and 90). An opening (84a, 94) is machined through an outer surface (26) of the head (30a) to define a passage (82, 92) interconnecting the first and second cooling cavities (80 and 90) to provide for communication of cooling liquid therebetween. The opening (84a, 94) is closed. The throat area of the passage (82, 92) may be selected to control coolant exchange between the first and second cooling cavities (80 and 90) and additional passages may be machined in each head (30a) to provide additional coolant interchange or to vent air from the cooling cavities (80 and 90).
