The cooling jacket is supplied with coolant in proximity to portions of the cylinder head that support the exhaust valves and coolant is discharged from outlets formed in portions of the cylinder head that journal the intake valves so as to insure uniform cylinder head temperature. The invention is disclosed in combination with either single or multiple spark plug arrangements and in each embodiment at least a portion of the spark plug is also surrounded by the cooling jacket.
