The invention relates to a metallic cylinder head gasket for an internal combustion engine, having a cover plate which faces the cylinder head of the internal combustion engine in the installed state and is provided with one or more openings arranged next to one another, corresponding to the combustion chambers of the internal combustion engine. The cover plate has a bead around each opening with a space between the bead and the opening. This leaves a straight sheet metal portion in the edge region of the opening. Arranged adjacent to the bead around each opening radially inwards from the respective bead facing away from the cylinder head is a stopper for the bead, which at the same time forms an upward combustion chamber extension of the seal. In this case, the stopper decreases in its thickness radially outwards in such a way that the surface pressure in the region of the stopper is essentially homogeneous over the width of the stopper under operating conditions.
