ARP Pro Series head bolt kits are application specific -- designed for use with typically competition only components. These fasteners deliver superior strength and meet the ARP "zero defect -- zero failure" quality standard. Hardened and parallel-ground washers are included with each kit to ensure even load distribution and accurate torque readings. They feature reduced wrenching 12-point heads and wide area flanges to eliminate the need for valve train removal for cylinder head retorquing and permits the use of larger diameter valve springs. This kit is for select Toyota applications (7M GTE, Supra).

ARP is THE name for performance head bolts. For high performance engines you will want to use these vs the oem!!
