so i go to change my plugs and cylinder 2 and 4 the plugs themselves have the nut section of it completely broken or stripped off , now i need some opions on how to get em out without takin the head off, i was thinking a snap-on reverse socket would be able to pull em out, anyone have any ideas?

 

How broke are we talking? Thread is the only piece left or is there still pieces of the nut left?
