Run it up to a runnin' temp before retorquing.
I don't have enough experience with the motor in the H to say for sure but, if it's anything like the 133s/123/ it's quite cold-natured and will take some time to warm up. You can speed the process along by running her for an hour under some kind of load. If you can't put that together, you can also run it with the radiator covered with something like a plastic trash bag large enough to cover the grill (the vacuum of the fan will hold it very nicely in place.)
In either case, you want to run it until it's not especially comfortable to hold your hand against the crankcase (with the water jacket behind it). The head will heat up sooner, but it's important to get the crankcase warm as well. That's working temperature.
But your question raises a question that I've never heard a good answer to, but then I'm not sure I ever asked). Should you retorque while it's hot, or wait for it to cool and retorque?
