Most of ARP's fasteners (and other good fasteners) have a rather large radius where the hed of the bolt meets the shank. If the washer did not have the "bevel" in them, they would not fit flush against the underside of the bolt head. Try it with yours, put the washer on with the bevel away from the bolt head and see if it will fit flush against the bottom of the bolt head. Hold it up to a light to see it good. If the underhead radius is real small, it might not make a difference, but that is the reason for the bevel.
Hope this helps,
