Maybe...Maybe not....
The idea is to get the ring as hot as possible WITHOUT getting the block hot so when the heat is removed the ring will cool as fast as possible. The ring will shrink the most this way and fall out.
If after heating or welding and cooling and the ring has been staked, a few taps with a punch on the inside all the way around will usually relieve the punch marks and loosen the ring.
