mark muray: No, that is 12 point head bolt, not head stud. There is a few different part numbers floating around, depending on where you buy from! 205 4601, 205 4602, 254 4009 also as what Sean mentioned lol. At the end of the day, just buy the 1 off fleabay from engine parts 24/7 unless you can get trade price.
