It is stock GM.I boaught a zz 502 that I have torn down and are building for marine use.The factory ring end gap was .024 already wich I found interesting seeing as these motors are getting such a bad rap for marine use,for such issues as this.I am glad I tore it down cause the block had a casting pitt in one of the bores and had tobe repkaced.
