A steel laminate gasket is used for an internal combustion engine having at least one hole therein. The gasket comprises a main plate, and at least one pressure regulation plate. The main plate includes a base section having at least one first opening corresponding to the hole of the engine, a flange situated over the base section around the first opening, and a curved portion situated between the flange and the base section adjacent to the first opening. The curved portion has resiliency to seal around the first opening when the gasket is tightened. The base section, flange and curved portion are integrally formed together. The pressure regulation plate is placed over the base section and includes at least one second opening. The diameter of the second opening is larger than the diameter of the flange so that the pressure regulation plate can be directly placed over the base section without laying over the flange.
