piston ring stuck on piston

on one of my pistons, i cant get 2 of the rings off. all the other rings were loose and i was able to pull them off, but these 2 are on it tight and theres not room to pry them off.

junking the rings or saving them ?

might need a few taps with a tammer that wont mar them, or a soak in some thinner to loosen them up

i have new rings to go on.
i’ll have to get something to soak it in i guess
