Flatness is 0.1mm across the surface.  Audi state that restoration
("Instandsetzung") is not possible.

The insertion of new guides is described in the microfiche, and thus
probably in Bentley.  One or two things to watch for.

Personally - once the thing is off and in a professional machine shop -
I'd do the guides and the valves.  Especially the exhausts.
