3.3 EFI Rebuild

[WHT85Berlina]

I have totally stripped down my 6 cyl black motor and found that there is quite a lot of black stuff built up on my pistons and on the valves. As this is my first project and to be honest I dont know alot about this stuff I have no idea how to clean it all up safely without damaging the motor or is this a sign that the motor is tired and neads some more attention that I cannot offer?

Also any suggestions what else I should do to the engine whilst it is out, stripped and on a stand?
