The 2 outer layers are designed with a reverse embossment to interact with the inner layers. Once compressed, the outer layers are forced into the bore-stop layer. This provides a superb combustion seal, even with high-compression applications. Kit for Evolution Big Twin contains 2 multi layer steel head gaskets and 2 silicon beaded metal base gaskets. Kits for Twin Cam contain 2 multi layer steel head gaskets and the cylinder base O-rings. Each gasket is coated on both sides and embossed around each oil passage, thus no additional sealers are required.\u003c\/p\u003e\n\u003cp\u003eFits stock 3 1\/2\" bore 80CI\/1,340cc Evolution Big Twin (OEM 16773-85)\u003c\/p\u003e\n\u003cp\u003eMultiLayerSteel Head Gskt set BT84-99\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Special \u0026amp; Big Bore Gaskets\u003c\/li\u003e\u003c\/ul\u003e","brand":"James Gaskets","offers":[{"title":"Default Title","offer_id":62566230294858,"sku":"231667","price":1105.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/standard-rgba_aef16386-8ae7-49d0-9fec-2cac00230565.png?v=1782766451","url":"https:\/\/partsdenmark.se\/products\/james-multi-layer-steel-head-gaskets-for-evolution-and-twin-cam-gasket-seals","provider":"Parts Denmark","version":"1.0","type":"link"}
