One Other Thing To Check (While Your Under Your Truck)

Yeah.. blue loctite should be used on the oil pan bolts. I doubt you'll do anything to the oil pan. Worst case would be a twisted head that comes off the bolt. Anyways when you torque a bolt you're applying holding pressure on the block threads and bolt threads. With that said the thread will flex a little and causes pressure. To much pressure and you'll end up with broken thread (stripped bolt).
What happens with vibration (aircraft or small engines) is when the bolt is is torqued it creates a glazed surface. The loctite dissapates that and gives the bolt something to hold onto. Not to mention the liquid will expand and create more down pressure. As a rule of thumb you should tighten the bolt to spec and always do a 45 degree turn if it's in a high vibration enviroment. Oil pan bolts are not really high vibration. Something like a flywheel or piston rod you need to be careful.
I wouldn't worry about it

Safety wire the bolts to each other in such a way that they can't come loose, because they are attached to the bolt next to them. Small hole drilled through the head, so that a small wire can be slipped through it, and then twisted and then run through the hole of the next bolt,
