Abstract: An engine includes an engine block and a cylinder head mounted to the engine block. The engine block includes a bore elongated along an axis and a liner disposed in the bore and extending annularly about the axis. The liner includes a seal surface and a fire dam disposed radially inward from the seal surface. The fire dam extends along the axis from the seal surface towards the cylinder head. The engine further includes a head gasket disposed between the engine block and the cylinder head. The head gasket extends endlessly around the fire dam. The engine further includes a shim seated between the seal surface and the head gasket and abutting the seal surface and the head gasket. The shim is disposed radially outward from the fire dam and extending annularly about the axis.
