you should have ten bolts for the head and two smaller bolts that go into the front cover. are they head bolts or head studs? if they are studs that screw into the block and have a nut that holds down the head then they are re-useable. if they are bolts they are torque to yield and can only be used once. you can get them here http://www.store.partsdinosaur.com/page329.html for about $44 shipped
