Oil Pan Gasket help
Can't say for sure on your question, as I don't remember how mine went together.
With that said, ifn you're doing this with the engine in the car, (read PITA), I would take the time to make sure the pan rail is flat around the bolt holes, then I would lay the gaskets out on it with a thin bead of silicone and let it set up for a bit, that will help hold them in place while you're fighting it to get it back in.
And for sure use some silicone where those meet.
