I e-mailed ARP and the guy I talked to said that they don't have an application for rod bolts for 03/04 cobra's. Do we need to use brand new factory rod bolts or what? Also, in there catalog there is only main bolts for 2 bolt main's not 4 bolt. Do we use these bolts for the main caps and have to use factory bolts for the two that go through the outside of the block? As far as the head bolts, which are better to use, the Hex or 12 point?
