It will depend on if a lube or dry torque, type of washer used. If lock washer is used then less torque is needed to not damage the lock washer. It should be about 170 ft/lbs max dry with flat washer, if it leaves an imprint in the metal (head or washer) it is too tight. In this case use less torque or down grade. Please note that the washer side is normally the side torqued, regardless of where the washer isi.e. head or threaded side, if concerned then washer both ends.
The torque needed to loosen a bolt or joint is often much higher than the torque needed to put the bolt in in the first place. There is no set value difference between the two, unfortunately.

Once the initial torque is applied to the fastener, a reverse torque test can be performed to make sure that the fastener has not loosened due to vibration or other conditions like material fatigue or yielding. So, lets say you tighten a bolt to 150inlb with a torque wrench. You should be able to take that torque wrench and apply 150inlb to the bolt in the reverse direction without the bolt loosening (reverse torque is gretaer in almost all cases, depending on materials because initial static friction must be overcome.)
