Want to verify which plugs to use. I was told Champion J6J. Any other thought suggestions?

Ya the j6j was what was recommended back 1948. It is no longer available so we use j6C, same heat range. Some people only use NGK other fellas use AC they will all work fine. It’s like arguing which is better Ford or Chevrolet! Pick your poison!
