Hi,
do the valves on the 1.2 8 valve engine have to be removed before i get the head skimmed?

Technical skimming cylinder head

No. Tiny pieces of this soft aluminium are relatively harmless.
But how is a new head gasket going to cause all of the cylinders to burn fuel more efficiently??
Did you get a compression check?
Your sooty spark plugs point to an air fuel problem that is identical for all cylinders rather than a leaking head gasket.

Why do you want the head skimmed? Has it been carefully measured and deemed no longer flat?
In my time in the motor trade I've seen so many heads skimmed, and so few were necessary. If there is no surface damage, like where a gasket has burnt, a skim is probably unnecessary. Even non-flat a little beyond the spec will usually tighten down and cause no issues. When heads are clamped to the block in service, they do not warp, unless they somehow manage to stretch some head bolts. Removing them while still hot can cause distortion as they cool, but this is unlikely as they are cool long before all the ancillaries are removed ready to lift the head.
Save the time and money and stick it back on.
