A 3 phase 20KW heat package at 208 volt service would only need a single 3 pole breaker of 70 amps(a single 3 pole at 240 volts).
The heat kit for that Goodman is still made, and so is the control board for it. Don't install a heat kit in it if you don't have the control board. As some of the safeties must go through the board also.
