Re: Terriable backfiring
Tom and Steve have great ideas. Even if you have previously tried Steve's suggestion but not Tom's, do Tom's and try again. You can actually run the motor. As the head lifts the distributor/cam shaft should raise with the head, and immediately shuts off the motor.
I had a particularly stubborn head, the mechanic tried this method, did not have a puller, tried using a motor hoist and had the front end off the ground, had to resort to soft wedges. Ends up there was so much rust from sitting for 50 years with a bad gasket he was not sure a puller would have worked.
