You should be just fine. It may not be the heaviest corn, but those yields are still at least 20-25 percent more than 25-30 years ago, too. You're only talking two less rows now, than what the 8820 was used to, when corn was around 110-140 bpa.
Good luck with the 8820's. One will have a nice home, for sure.
