Oh, don't use a gasket. There is not a factory gasket for that, the stupid aftermarket ones never line up and the oil pan always ends up getting deformed then in 5-10 years you'll need to remove it for some reason and it'll disform the pan more leading to more future possible leaks. Use a good oil resistant RTV like black or go to the dealer and buy their super happy fun best sealer and never worry about it again.

Like JBFP said make the pan flat and keep it flat.
