Not with the cab on. You wont get the outside, rearmost bolt out, nor get the stud in without taking the head off. When I first looked into doing studs, I called a local diesel shop, and this is how they wanted to do mine (cab off, swap one at a time). I didnt feel safe doing it this way. Good thing I did it my way (cab on, pull heads). I had one gasket that was beginning to fail in three areas. Along with white spots on 4 pistons.
It seems like that is playing with fire on an engine that is known to have issues in this department.
