After torquing my head down on Cylinder 1 to measure the Deck Height when I went to remove the head one of the Head Studs came off with the Allan head nut on it. I can't seem to remove the Alan head nut, placed it in a vice with a rubber cushion on the stud but it didn't budge.

Can I Just tighten the Stud with the Alan head nut on it to the proper torque when I assemble the Head and Cylinder?

Thanks
