ARP Main Bolt Washers

With the sharp edge of the washer against the radius under the head of the bolt you could be causing a stress riser that may cause the bolt to fail. What is the probability of this happening? Don't really know but it's like a small.

If it were me I would pull each bolt one at a time an flip the washer then torque the bolt to just below the final number. Once all are done go over the bolts in the proper sequence to bring them to the specified torque.
