Now that I hear it better, I'm with Tim. Get new cross over tubes too. You know where the torque wrenches are.

Work real clean. Before you disassemble, power wash your the indents where the lines go, get them as clean as possible, especially the ones in the back. I would get in them with a brush and clean them with engine cleaner and then pressure wash them as best you can. #6 tends to hide a build up of greasy crud out of site. Since you have to braille the tubes in, there's a chance you can catch some crud on the end of the tube. Could screw the injector. If in doubt, take the tube out, clean it, and start over inserting it. I did my number 6 several times. It lived.

Make sure the oil is out of the injector retainer bolt holes. You could hydraulic the bolt and break it. Keep an eye on the valve spanners. If you recall, I lost one, never to be seen again. It's not in the motor. . . .
