if you have not had any thing done to the crank i would grind all shape edges off the crank evey were with stones and then finish up with a sanding drums up to 80 git then and i sanded the counter weights with aDA and 80 grit and drums sanders i would tape off the oil seal and nose of the crank use rubber to keep the steel shot from hurting the seal and nose then off to get shot peen hits the crank and helps normalize the crank and you want to tape the journals off you do not want to hit them grinding . i like to radi the oil holes before i get the crank ground
