    2012 KK 3.7L stuck head bolts??!!

    .....am in to a head gasket set replacement job, 2012 KK 3.7L. Got all bolts out except for one each bank. Both are stuck, or at least very resistant to loosening further and rather than keep going and risk snapping them off does anyone have any suggestions?? Setting up a date with Mr. Heli-Coil...
