The Cometic copper head gasket for Toyota 3K/4K engines is an 84mm bore, .043 inch-thick copper gasket made from dead-soft copper. It compresses to conform the sealing area, requires less clamp load and is suitable where blocks have been machined for steel o-rings or extreme cylinder pressures. The gasket distributes load across the sealing surface and avoids sealants or re-torque in typical installations.
