A gasket for an internal combustion engine having a bottom copper layer, a graphite layer overlying the bottom copper layer, an aluminum layer overlying the graphite layer, and a second graphite layer overlying the aluminum layer. The bottom copper layer is then folded over an interior circumference or perimeter of the gasket to form a copper lip. A top copper layer may also be formed over the second graphite layer prior to forming the copper lip.
