Need help.

I have watched this film in the early 90…it seemed to be a movie about gangsters..renember only few scenes:

1. Killer is killing somebody in the sauna by locking door with wooden stick and putting temperature to highest level

2. Old gangster is dying.but waiting until he will receive head of his enemy. His sons bring him head of his enemy and he is dying.

3. House is surrounded  by police..gangsters are coming out and shot by police
