Abstract
A multi-layer head gasket having at least two active layers and a shim layer sandwiched there between. The gasket and shim layer include cylinder openings aligned with the cylinders disposed within an engine block. The shim layer incorporates a plated portion for adding topography to an otherwise flat shim layer, the areas of plating determined based on FEA and/or pressure film load testing, for improving fatigue resistance, sealing pressure, and/or loading characteristics of the gasket.
