The only post-install procedure after warm up is adjust the valves.
You can always re-torque the bolts... but like I said, the initial assembly was to oil the threads. Oiling the threads allows the bolt to stretch more and that is what creates the torque. Un-oiled threads most of the torque is from friction of the metal-metal contact. You can get 30% more torque from oiled threads than unoiled.
