A metal gasket for an internal combustion engine is installed between two engine parts. The metal gasket is formed of at least one metal plate extending substantially throughout an entire area of the engine to be sealed. The metal plate includes at least one bolt hole, a fluid hole situated near the bolt hole, a sealing device for surrounding the fluid hole to seal therearound, and a support bead situated around the sealing device without surrounding the bolt hole. The support bead is deviated from the fluid hole to balance surface pressure around the fluid hole when the engine parts are tightened. In case the gasket is formed of a plurality of metal plates, the sealing device and the support bead are formed on the different plates.
