head bolts. Follow ARP instructions: 25, then 50, then 70 lb/ft on the larger stud, then 28 lb/ft on the smaller stud. Large nuts are easily tightened. The smaller 5/16" studs aren't that great. The last pin on the first head just started spinning at 28lb/ft. For some reason I had an extra small stud in my kit. Cool, but I could do those Don't get the stripped nut off the stud. Quickly run to the Autozone to get 5/16"-24 Fine Thread Nuts. All said and done: 3 smaller nuts snapped off and damaged the studs. I know people have had luck with them and I know they cost 1/5 the price of Arp-Studs but they didn't do what they wanted. should be enough for me at least.
