Just use the good FelPro one-piece silicone oil pan gasket. It has nylon washers imbedded in the silicone gasket which makes overtightening impossible and they support the pan where the bolt tightens down on it and predetermines the amount of crush possible on the gasket so it will seal perfectly. Also makes getting a good seal at the corners where the joints typically are on a 4-piece a super easy thing to pull off. You DO have to flatten the bolt holes on a used pan to make sure the amount of crush on the gasket will be sufficient. I've never had to rework the metal of a pan since I started using these gaskets.
