Looks like it's stretched from the straightening process ,rather than work it any more place some 1/8 thick washers under the pan ,between the pan and block loosely install the 4 corner bolts (NO GASKET ) then start all the rest of the bolts using the largest washer that will fit in the oil pan rail ,Starting from the center slowly work out going from side to side to evenly tighten down the pan to it's mating surface , this should bring it back to a usable pan once gasket is installed . Try it it works .
