i had one stuck one on my 2.6 that stripped. i ended up having to weld a nut to the head of it. if you have to do that, pull the cam out for clearance and get ALL of the oil out of there. i layed several wet rags around the area i was welding too to help prevent fire. you could also try a large EZ out. be aware welding may warp/damage the head if you're reusing it...
