ABSTRACT:
A metal cylinder head gasket of the invention is basically formed of a metal plate extending substantially throughout an entire area of an engine to be sealed, and a plurality of cylinder bores and bolt holes. The cylinder bores are arranged in a longitudinal direction of the metal plate, and the bolt holes are situated around the respective cylinder bores. At least one shim is located at at least one of four corner areas of the metal plate without extending outwardly from the corner area where the shim is located. The shim supports a tightening pressure of bolts to thereby prevent deformation of the cylinder head. Sealing means for the cylinder bores and other holes can be equally compressed to help sealing of the cylinder bores and other holes.
