Abstract: An engine head gasket includes a base layer, an upper layer, and a lower layer. The base layer includes a base layer inner edge. The engine head gasket further includes an anti-preignition wrap defining a cylinder opening and wrapped around the base layer inner edge. The engine head gasket is configured with a combustion seal and selective thicknesses to direct a combustion sealing load to a cylinder block. The anti-preignition wrap shields angular corners of the base layer inner edge from a cylinder to limit preignition.
