so in the process of removing the two block plugs on the back of my block for the install of a breather kit the passenger side cap decided not to come out, i used a 14mm allen key+air tools, i tried to be as careful as possible but the cap strips very easily and it would not break free...the driver side came out how-ever the pass side is basically stripped

what is the best/easiest way to go about removing it from this point?

intake manifold etc is all removed so i have a bit of space to work with..just looking for suggestions to save me headache and time'
