Take it easy or you may snap it off, then you'll have to pull the head. Hose it with penetrating oil, then give it a couple of medium whacks in line with the plug with a hammer, cross your fingers, & try again. When you put the new ones in, use some Never-Seize. OR, you can do like I do & give the car & the parts to your mechanic & let him do the work…
