PCT No. PCT/EP79/00063 Sec. 371 Date May 8, 1980 Sec. 102(e) Date May 8, 1980 PCT Filed Aug. 10, 1979 PCT Pub. No. WO80/00595 PCT Pub. Date Apr. 3, 1980.A water cooled cylinder head for an internal combustion engine which may be manufacturable by die-casting method in which all of the niche - shape water galleries are connected to the water jacket of the cylinder block through deformable openings in the cylinder head gasket surrounding the combustion chambers in which the openings are connected by cross channels and a lateral longitudinal channel. The upper limit of longitudinal channel is formed by the highest point in water galleries and cross channels wherein the longitudinal channel has a water outlet opening. A special arrangement of the niche-shaped water galleries, cross channels, and openings in cylinder head gasket with respect to the main components of cylinder head controls the cooling of the cylinder head in an advantageous manners.
