Column Shifter Help Needed

1971 Dodge Demon, column shift 727. I recently changed the steering column due to it getting hot while driving. 440 with fenderwell headers that 1 tube runs close to the steering shaft. The replacement column had no issues for a 100 mile trip. Last night, after about 30 miles, it started acting up. It now shift when steering, like the shift mechanism is hanging up or sticking on the steering shaft???? I made it home but as is it is almost undriveable.. It also gets hot now again like the old one. Anyone experience this before?
