In theory the cam gear can be reinstalled by first heating the gear, I didn't want to risk damaging the gear by trying to pull it or with my luck only getting it half way on before it cooled too much to go on so i went ahead and pulled the cam.
Either way the rocker arms and push rods need pulled. At that point the only extra work is pulling the radiator which is attached to the frame with 4 bolts. My mistake was pulling the radiator out the top. Since doing mine I heard the radiator can be dropped out the bottom which should be much easier.
When I reassembled the valve train, I went ahead and resynced the injectors and reset the fuel setting, I am not sure this had to be done but went ahead and did it anyway.
