A cylinder head gasket for an internal combustion engine includes a substantially flat center plate and first and second spring plates disposed on opposite sides of the center plate. The center plate has an opening therein. Both the first and second spring plates have openings therein aligned with and smaller than the opening of the center plate. The first and second spring plates thereby define wire ring retention portions of the spring plates extending radially inwardly from the edge of the center plate opening. A wire ring having a wire diameter greater than a thickness of the center plate is disposed between the ring retention portions of the spring plates. The spring plates have a substantially wave-like concentric embossment encircling the opening in each and radially proximate thereto. Clamping the gasket between two sealing surfaces forms a primary combustion seal at the wire ring, and forms a secondary combustion seal beyond the ring at the embossments.
