Just make sure they are replaced into their original position if reused. You will be checking to make sure the hydraulic piston is not stuck or sticking. They are the end of the oil train and have no relief port so get fouled from old oil and debris causing sticking and leading to failure. One of the casualties from adhering to Porsches oil change schedule.

edit: If you search there is some discussion on this and the use of BMW lifters to replace.

edit2; attached a thread with some options.
