Just after some advice on upgraded head gaskets please.
I am doing the valve stem seals on my (2002) 888, I thought it would be a good idea to upgrade the head gasket while the head is off.
For the people who have done this:
Where can you get a 'Group A' head gasket from?
What are these 3 & 4 layer had gaskets on ebay like? - Which one is better (3 or 4 layer)?
Is there any other jobs worth doing whilst the head is off? I will be doing an upgraded head gasket, valve steam seals, re-grinding valves back in and cleaning etc.
