Sometimes you don't get them out without destroying them. The one I had difficulty with, I "pushed" it out part way from the back end with a sawed off broomstick and a hammer. Then I pulled it out with pliers from the front end. This caused some damage to both ends of the tube but not severe. The other 56 head I have, I cannot get the tube out without destroying it. So the tube stays and I still have a useable head.
The tubes came out of my 57 heads without much problem. I think it depends on how much rust buildup is in the head. It might help to "tank" the heads first.
Such issues may be in part the reason Pontiac abandoned reverse flow.
