Not easily removed on these, if it starts ok, i would leave it as it is. Trying to remove it would mean drilling down in to it & using a stud extractor & then if you still can't get it out & you've drilled too far you may lose compression through the hole that you've drilled & debris may fall into the cylinder. Removing the cylinder head would be better if you really want it out.
