This is important in engines with high power adders such as turbochargers, superchargers or nitrous. They can even be a great addition to a mildly modified build as insurance against failure. These head bolts are manufactured from aircraft quality 8740 high tensile strength chromoly steel and cold-forged to ensure molecular integrity within the bolt. Meaning these bolts are rated up to 190,000 psi making them stronger than Grade 8 and OEM fasteners. All kits come complete with hardened parallel washers for an even load distribution and accurate torque readings.\u003c\/p\u003e","brand":"Aeroflow","offers":[{"title":"Default Title","offer_id":41674575183953,"sku":"AF37-2111","price":238.94,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2115\/6365\/files\/AF37-2111.jpg?v=1719982129","url":"https:\/\/longboostperformance.com\/products\/head-bolt-kits-b-b-chev-396-454-suit-aeroflow-320cc-and-edelbrock-performer-rpm-cylinder-heads-af37-2111","provider":"LongBoost Performance Parts","version":"1.0","type":"link"}
