An engine head gasket comprises a relatively incompressible steel plate having compressible tubes with a thermally expandible non gaseous non compressible elastic media therein disposed within each combustion opening and elastomeric sealing beads molded about each coolant and oil flow aperture in the head gasket. Shim plates are utilized on each side of the steel plate as compression limiters for the sealing elements. The shim plates also function to retain the tubular combustion seals in place.
