This is true, but as far as we know from post #1 the OP has not removed the valve cover... yet. Nor did he say it snapped back. I was just making a suggestion as to why he might have so much movement. https://youtu.be/_dnBoiVobO8

Sounds like you may have a "B" distributor with centrifugal advance. A "B" distributor advances 8½° (17° crank advance).
If you have 25° movement in addition to what the distributor advances I would venture to guess you have some serious wear problems...
