A multi-layered cylinder head gasket for positioning between a cylinder he ad and a cylinder block of an engine includes upper and lower compression layer s and a stopper layer. The compression layers and stopper layer all include aperture s that mate together to define a peripheral edge. The stopper layer further include s a folded portion and a main body portion. The folded portion has a plurality of waves that contact the main body portion of the stopper layer to form a stopper when folded over. The stopper is positioned at the peripheral edge of the mated aperture. The waves deform under high compression loads generated by the joining of the cylinder head and the cylinder block. The deformation balances the stresses generated by t he compression loads around the mated aperture.
