Some say an hour, others 3 hours, i run it a few hours at light load, let cool for few hours or over night and then check torque.

 

Depends mainly on the model of engine and if OHV.

I think the service manual has a recommendation for this. If I remember right you run the engine til it's hot, maybe 15 minutes, then shut down and re torque. I did this on my K321 HG job and it's never leaked.  In the manual there is a also a recommended sequence for torquing the bolts.
