Head gasket sealing is more often than not the Achillies heal of building for power. Increased combustion pressures will try to lift the head and reduce the sealing effectiveness of the gasket.\u003c\/p\u003e\n\u003cp\u003eAll ARP head studs are centerless ground for concentricity with cold rolled threads for maximum fatigue strength.  ARP2000 alloy has a 220ksi tensile strength.  The studs are undercut to more effectively compensate for head gasket compression.  All head studs feature a broached allen hex in the end of the stud for easy installation.\u003c\/p\u003e\n\u003cp\u003e11mm is the factory thread size so no machine work is required, and they are a direct replacement for the factory head bolts.  It is essential to follow the supplied instructions and use the included ARP thread lubricant.   Use only an accurate torque wrench of known calibration to ensure best results.  Any fastener \"spring back\" detected at any point during the torque process will require the washer to head surfaces to be meticulously cleaned and the stud re-torqued in order to achieve accurate torque values.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eManufacturer Part Nos. \u003c\/strong\u003e260-4702\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat it fits:\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEJ SOHC (Non-Turbo)\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":44394762534966,"sku":"ARP-S4702","price":311.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/5143\/3782\/files\/arps4702.jpg?v=1764474263","url":"https:\/\/www.rallispec.com\/products\/arp2000-head-stud-kit-11mm-sohc","provider":"Rallispec","version":"1.0","type":"link"}
