A combustion seal for a cylinder head gasket of an internal combustion engine includes a corrugated rigid carrier having a radially extending base portion, the radially innermost peripheral edge defining a portion of a cylinder bore opening, and three channels defined radially inwardly of the base portion and radially outwardly of the inner peripheral edge. The radially innermost and outermost channels open in a first axial direction while the channel disposed between them opens in the opposite axial direction. An elastomeric ring is received in all but the radially outermost channel, first face of the rings in facial contact with a root of the channel and an opposing second face defined outwardly of the channels when the seal is in a relaxed state. When the gasket is installed, the elastomeric rings elastically compress to become generally flush with the walls of the channel in which they are received.
