I did this in 1992 with the 1962 Imperial I used as a daily driver in that era. Car ran perfectly for another 90,000 miles. I used to drive it from Chicago to the Chrysler Nationals in Carlisle every year.Forget the 440. Change the valve seals and the oil and drive it. If it doesn’t clear up then Re-ring the 413 and do the heads. You don’t need new pistons on and 83k mile engine.
