Oh wow. That is surprising that they are that different.
However, oil pan bolts are fine to reuse because you are not tightening them that much. The ones that you need to be careful of are head bolts that are actually stretching the bolt. They are called torque to yield bolts. These are not so I always reuse the oil pan bolts.
If you are going to use Loctite then just be sure to use the one that says it is removable. Clearly these need to come out so you don't want them getting stuck and then stripping or braking if you have to remove them again.
Thanks for the update with that info. That will help others that visit the site with the same question. Thanks
