You can drill them and try to use an easy out to get them out or drill them completely out and retail the holes

Yes they are going to have to be drilled out, use a left handed drill bit that way if they do get a good bite some times they will back right out while you start to drill then you won't have to chase the threads or worst case heli coil the hole.
