Re: ARP Head Studs
I do as rotorwrench does, on camshaft nuts, to clean the cam threads. As accurate as most things are machined, cams are different. All threads are not the same, only close. Same with the 2 dowels, most are 5/16", .312" but I've found many that are only .310". Some holes get worn, probably from being a bit loose. For these, I make oversize dowels, both in diameter and length.
