The flange must be flat period. Any unevenness will cause a leak. When the bolt hole area has a gap, torquing the bolt would cause another area to raise up.
The gasket is only for microscopic imperfections that cannot be felt or seen. A gasket wont be able to seal a big gap like that.

Got a call from the shop before they closed up, still havent evened out the flanges. They are having to do more grinding than originally expected. This is ridiculous for a brand new part.
