A gasket having a gasket plate formed with an aperture. An annular flange provides a stopper seal around the aperture. The flange has spaced areas of varying thickness. The gasket is formed by punching an opening in the gasket plate inwardly of an annular array of bolt-holes. An annular portion of the plate surrounding the opening is folded back to form the flange and place it in surface-to-surface contact with the plate. The areas of the flange adjacent to the bolt-holes are compressed a greater amount than areas of the flange more remote from the bolt-holes.

A cylinder head gasket includes a main gasket body having at least one cylinder opening, a wire sealing ring, and a metal armoring ensheathing the wire sealing ring. The metal armoring has a first annular flange portion extending beyond the cylinder opening in overlying relation to a first main surface of the main gasket body, a second flange portion opposite the first flange portion having a size no greater than that of the cylinder opening, and a curved portion joining the first and second flange portions. The cylinder opening is notched to receive lock tabs of the second flange portion through the main body, after which the metal armoring is rotated to offset the lock tabs from the notches to lock the armoring and sealing ring within the cylinder opening.
