Claim:
A seal for the head gasket of internal combustion engines comprising: a bead seal of material that is elastic, resists compression and deforms under pressure; and a malleable copper head gasket having a plurality of apertures wherein for each selected aperture; a first bead seal is attached to the malleable copper head gasket on a first planar surface around said selected aperture on a cylinder block side at a first distance from said selected aperture; a second bead seal is attached to the malleable copper head gasket on a second planar surface around said selected aperture on a cylinder head side at a second distance from the selected aperture; and upon compression of said malleable copper head gasket between a cylinder block and a cylinder head, said malleable copper head gasket deforms creating a trough in said first planar surface and said second planar surface at each of said first bead seal and said second bead seal positions.
