Made in USA, SCE Pro Seal composite head gaskets are simple but trick. These high performance head gaskets are constructed of three components, graphite-kevlar facing mechanically clinched to a perforated steel core with steel-backing & fire ring armor. A strong but compressible gasket which will not damage aluminum cylinder heads from fretting or friction brinnelling. Steel back construction is strong enough to withstand high compression and mild power adders.
