A cylinder head for a water-cooled internal combustion engine has a lower and an upper cylinder head portion fitting over one another along a parting plane traversing cooling chambers complementally formed in the lower and upper cylinder head portions. The lower cylinder head portion has intake and exhaust ports and is tightened to a cylinder block. The upper cylinder head portion carries a valve operating assembly of the engine. A cylinder head cover is situated above the upper cylinder head portion and covers the valve operating assembly. The lower cylinder head portion has a circumferential lower wall bounding a liquid-guiding chamber provided in the lower cylinder head portion and serving for returning oil from the upper cylinder head portion. The lower cylinder head portion also has a circumferential upper wall constituting an upward continuation of the lower wall and extending from the intake and exhaust ports. The circumferential upper wall has a circumferential seating face supporting the cylinder head cover. The upper cylinder head portion is not in a direct contact with the cylinder head cover.
