could you use a 12pt head like on an ARP bolt to help with clearance ?
That would not help me the bolt is just on the edge of too long.I can grind off .050" from the length.The bolt I got with the vert had no threads past the nut What I ended up doing is taking a feeler gauge and checking the gap after I ground .035 off all the bolt threads and ended up with .080" befor tqing the bolt[about 2 threads gap]
