anything with a moh of 2.5 or higher will warp....
anything with a moh of 2.5 or higher will warp. basically if it leaves an anchor pattern it will peen the outside of the metal and stretch it. if blasted at a 45 degree angle it will not peen as bad....
Could it be a 10114182? If so, it is a Gen V 454, 4 bolt 1991 (or later). Hope that helps..
