After reading your OP again, why are you taking off the oil pan? Has it proved to leak? If that is your main job, do it and be done with it. Do not use a gasket, only RTV like the factory. If you are not certain about a leak, just clean off the area and drive a little to determine precisely where it is. Guessing costs time, energy and money. Finding out for sure costs a lot less of all three.
