One of the downsides of having a leak free motor is that these studs don't get the "rust preventative coating" that would prevent that sort of thing.
I suspect that climate may shape how one feels about this. The studs I see here in the New Hampshire tend to have rust on the surface in places and the nuts have some corrosion. When I remove the heads I tip the motor up on its side and fill the inside of the barrel nuts with some PB Blaster and let them soak a while. When I go to remove them they make a "ping" sound as they break free. I haven't tried this with a torque wrench so I don't know if the torque to overcome the corrosion is higher than the torque spec.
