The dear cylinder head seal

Hello municipality
My cylinder head gasket licks and licks. Not so bad, actually, that she has to be done tomorrow. Until the next belt change and DüF there are still 50tkm. Drotzdem is uncomfortable.
Since I will be very much in Freiburg in the Breisgau for the next two months, I think I'll allow myself to do that. So I'm going to get offers.

V8 3.6 0191 Automat 225tKm Engine in very good condition. No day, day, day, pulls well, although old ignition distributors and cables, pleasant consumption (12L) but just, very faithful engine.
My plan: compile material list.
Create a job list.
In the case of a contract, the Commission may request the following:
Ask yourself: Help me to do these tasks.
When changing the cylinder head seal: What else should be done?
Material list with part number?
Oil change: filters, seals....
==References== ATF change.......
To have all the ideas.
@ Pure B.
I see you're from the Freiburg area. Do you know anyone who does this?

Gruss and a never ending weekend
