By re-designing a smaller bore gasket, we increased the amount of gasket material between the bores another 0.15\" for better durability . This is advantageous on small bore LS engines with higher cylinder pressures such as those found in power adder applications. These feature .055\" thickness spread across 7 layers of steel. DESIGNED TO WORK Â WITH A TRICK FLOW FAST AS CAST LS1 HEAD. May also work with other aftermarket cylinder heads.","brand":"Brian Tooley Racing","offers":[{"title":"Default Title","offer_id":61757067919730,"sku":"BTR-058420","price":75.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0960\/6643\/7490\/files\/hyper-motive-image-coming-soon_36325f53-05d4-4579-9821-c386324e18d9.png?v=1775963168","url":"https:\/\/hypermotive.com\/products\/btr-small-bore-ls9-head-gasket-sold-individually","provider":"Hypermotive Performance","version":"1.0","type":"link"}
