Need advice 360 timing chain cam/crank slightly off

There's one more scenario, and I've pointed it out before. What is stamped on that top gear? does it have both "S402" and "S296" on it? 402=LA 296= Poly. They look the same and, in all regards, are the same ECEPT the timing. It's different by 1 tooth.
