If they won't turn at all, is it possible that you are being conservative with the 3/8 ratchet? Can you put a torque wrench on it to tell how much torque you are applying?
I would think (and this is just an estimate) that the plug could handle at least 60 ft.-lbs. I'm not sure of their internal construction, however, a 1/2" cap screw is good to 120 ft.-lbs. I would think the threads on the plug are something around 12 mm.
60 ft.-lbs. would be difficult to apply with a 3/8 ratchet.
One other possibility:
Get an impact wrench and lower the air pressure down dramatically. Test the wrench on another fastener to ensure that the maximum torque you can get out of the wrench is about 50 ft.-lbs. Be positive of this. Then set the wrench up on the glow plug and let it hammer away for a few minutes.
If you heat the plug with a propane torch before you do this, I am fairly sure that you will be successful.
