The best advice is to read the POH for the particular aeroplane and nail the correct speed. If you are really high there is a good chance of reaching the nearest airfield, but if not the priority must be to select a decent field and landing in it - having gone through the re start drills. Charles Church died because he tried to nurse a failing engine home. He crashed in a small one having flown past some really good ones.
I've only had one proper failure and that was in a twin ( a Dove ), and it's true what they say: "it takes a little longer to get to the scene of the crash in a twin"! I just made it into Dauville in a gradual descent ft from 5,000ft with the good engine on max continuous, which made it start to fail!
