ABSTRACT:
A metal gasket assembly for a cylinder head includes a pair of elastic metal substrates each having an outer shape which conforms with the outer shape of the gasket assembly, cylinder openings corresponding to cylinders in the cylinder head, a peripheral region surrounding the cylinder opening, which may be greater in thickness than remaining region of the relevant substrate, and a bead in the peripheral region. The substrates are superimposed with each other with top portions of the beads of the substrates in abutment with each other. A by-plate may be arranged between the substrates and has an increased thickness in its peripheral region which surrounds the cylinder opening and which is in direct abutment with the top portions of the beads in the substrates.
