It replaces the stock cylinder head bolts with studs and nuts, a solution that distributes the load more evenly across the gasket and does not wear out the block threads every time the cylinder head is removed.\u003c\/p\u003e\u003cp\u003eThey are manufactured from 8740 chrome-moly steel, heat-treated by ARP itself to a tensile strength of approximately 190,000 psi. ARP centerless grinds each stud after heat treatment to ensure it is straight and concentric, and thread-rolls it at the end of the process; this achieves a fatigue strength approximately twenty times greater than that of a thread made before heat treatment.\u003c\/p\u003e\u003cp\u003eFollow the torque and tightening sequence in the ARP instructions, which are calculated for their assembly lubricant; using engine oil will change the actual torque. If you have any questions about whether this is the correct part number for your engine, write to us with your engine code and year.\u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":53893677056334,"sku":"ARP-203-4206","price":281.31,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/7329\/0062\/files\/203-4206.jpg?v=1790662673","url":"https:\/\/driftandgrip.com\/en\/products\/arp-head-studs-part-no-203-4206","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
