Claim:
1. An internal combustion engine comprising: a cylinder block defining a block deck face, first and second cylinders, and a block cooling jacket, wherein the first and second cylinders are adjacent to one another and separated by a block bore bridge; a cylinder head having a head deck face defining first and second chambers, and a head cooling jacket, the first and second chambers adjacent to one another and separated by a head bore bridge, wherein the first chamber and the first cylinder form a first combustion chamber, and the second chamber and the second cylinder form a second combustion chamber; and a head gasket positioned between the cylinder block and the cylinder head, the head gasket having a block side and a head side; wherein the block cooling jacket has a first saw cut and a second saw cut intersecting the block deck face on either side of the block bore bridge; wherein the head cooling jacket has a first channel and a second channel intersecting the head deck face on either side of the head bore bridge; and wherein the head gasket defines a cooling passage fluidly connecting the first and second saw cuts with the first and second channels such that coolant flows from the block jacket to the head jacket to cool the associated bore bridge, the cooling passage of the head gasket having an inlet on a block side of the gasket fluidly connected to a first outlet and a second outlet on a head side of the gasket; and wherein the cooling passage of the head gasket is y-shaped.
