A cast cylinder head of light metal incorporates a reinforcement made of a stronger material than the light metal. The reinforcement consists of a relatively narrow elongated steel plate (6) which stretches in a single piece along all the cylinders. The elongated steel plate (6) is provided with transverse arms (8) which stretch out approximately perpendicularly from the steel plate between the valve port apertures (3a, 4a, 5a, 6a) of each cylinder. <IMAGE> |
