Replacing injector valve cover help?? Lb7
 

I am replacing my injectors and have got everything out of the way on the drivers side so far and am ready to remove the valve cover, but I have ran into a problem, might be something simple but I was getting frustrated so I thought I would see if anyone has a tip or two. So when removing the Allen bolts I have 3 left right against the firewall that are a pain to get to and I really don't want to strip them out. Any help on removing them??? So far I have been using a Allen socket on some and a couple I was able to put a Allen wrench on and turn with visegrips but I can't get to those last bolts with either of my techniques

I used an Allen socket and wobbly just made sure it was seated solid in there, best of luck to you some of them are a pita
