A couple of thoughts ...

1. Cornsnakes are not ball pythons ... ball pythons are natural 100% rodent predators, corns are not (hence the feeding trickery needed for corns) ... One mouse a week live, F/T, P/K is all most of them will ever need ... No cutting, poking, slicing, or braining is necessary ... ever.

2. Temps in the low to mid 70's are putting your snake on the fast track to a respiratory infection or worse.

3. 82-84 on one side, 92-94 on the other 24 hours a day 7 days a week for a ball python ... find a way, make it work.
