Mopar Cast Valve Covers Problem

Anyone else have a problem with some of the bolt holes on the valve cover lining up correctly? The ones that aren't lining up correctly are the 2 in the middle on the bottom side of the valve cover. I have a stud kit to hold them in place and the stud is so close to the valve cover I can't get a washer on. I tried a bolt and there isn't enough room to get a wrench on them.
