This is a used regular length long head bolt. This head bolt will fit 364, 401, & 425 cubic inch Nailhead Engines. This regular length long head bolt will fit these motor sizes for the following years 1957-1966. Each head bolt will be wire brushed and cleaned before shipping the bolt out. The pictures are of a sample head bolt. This listing is for one (1) head bolt, if you need more then one change the quantity when ordering/buying. Please note this is NOT the special 1/4" longer head bolt used for 1963-1966 AC and non AC one piece metal alternator bracket. If you need this special 1/4" longer head bolts please see my other listings or ask. The 2nd to last picture in the listing shows the 3 different original types of head markings on the top of the bolt. If you have a specific request for a certain head marking type please let me know otherwise I will just pick one of the three types. The last picture in the listing shows all of the different types of head bolts used on Nailhead engines (the one circled in red is the bolt style you will receive). Please ask questions.
