On a previous build for a tta I ordered a set of arp head bolts that were for a gn and they didn't work because some of the bolts on the bottom side of the head would bottom out on the shank of the bolt before they would tighten the head because the head isn't as thick there as a gn's. I ended up using a fel-pro stock replacement head bolt kit for an '86 lesabre. I'm putting another one together and don't want to use stock replacement bolts if I don't have to. Is there anything that I can order off-the-shelf from arp that will work? Bolts or studs.
