Well, I'm an aging ME so I don't remember most of this anyway. The Canton studs have an Allen end but they are all coarse thread and don't have a shoulder. The ARPs have a shoulder so they can be snugged into the block, and they are fine thread on top, but they don't have an Allen hole. Instead, they have a nose so the nut starts easier. I guess you can double nut them if you need to take them out.

They don't make a stud kit for FEs and the bolts they have for FEs are too short if you use a reinforcement. But the Pontiac/Mopar kit works. ARP 200-1901 and its variants for 6/12 point stainless/oxide. While these seem expensive at $70 for the kit, I priced out McMaster-Carr and the studs and nuts were more expensive, not the ideal size, and not as strong. So not a bad deal.
