I took notes in 2021 when I did my timing cover etc, wrote down the original bolt lengths. At that time ARP still didn't have any bolt kits which matched the needed lengths, only about half of their kits had useful bolts. I have two or three of those kits, I managed to save all but two of my old bolts. One was a bad replacement(wrong threads and length but they screwed it in), and one as too short(1/8" of threads). So I replaced two with generic grade 5 bolts, not perfect but close to the right lengths.
The lengths are wild, there are several different lengths, many 1/4" increments from 1/2" dimensions. To do it properly, the holes should be all measured anew, compared with the OEM, and new lengths chosen. Then ask ARP if they have those specific lengths, obviously without stud threads of course.
