A Land Rover independent in the south just did my '02 Td5 head gasket. Head gasket and work (inc. parts, consumables, head pressure test and skim, visual check 1 week later) was £1200.
I was lucky and the head passed it's pressure test when sent away. If I had needed it, they did say a new Turner head was £1200+vat.
While they were at it they did the water pump for £75.
Happy with the work, it runs better and smoother now!
