As others have said check the head to make sure that the head has not been overplaned. I used to plane these heads and too much can be taken off. You may be in the market for a new head if that has been done. Also check the threaded portion of the plug, the Champions might be too long. And as Lisa K said only use Autolite 437 plugs properly gapped. Champion plugs are not today what they were in yesteryear.

They are made in Mexico and have had problems with the shell breaking off in cylinder heads.Happened to me on an Olds V8.Most of the threaded part stayed in the head.It came out easy and showed most of the break was old.Had to be overtightened.Ive had some hard removals but never had a Champion plug break off before that one.I have plans to tap some some half inch steel 14mm and do a torque wrench test to find the breaking point of old and new Mexico plugs.Too much to do getting ready for winter now.
