[origin: US4854275A] Cylinder head for a combustion engine which has at least one web insert embedded in the cylinder head in the bridge region between the inlet and outlet valves. In order to prevent the occurrence of heat cracks at the root of the expansion joint receiving the web insert upon cooling of the cylinder head after its casting, the web insert has at least one opening, window or lateral cutout. Through this opening, window or cutout, the material of the cylinder head located on both sides of the web insert is directly connected together.
