You can do it either way. I left the turbo attached and was able to get the head out of the car by myself. I'm not strong by any measure. Note that I didn't say lift the head out of the car. If you do it this way, either remove the turbo oil feel line first or keep a close eye on it as you lift the head. It kinks easily.

When using the CD manual, check the CD for files with the same filename as the pdf section you're reading but with an A suffix. I find that the A suffix files generally have turbo specific information. Unfortunately the CD GUI doesn't tell you there's a turbo version of a procedure.
