Rocker cover removal

[Dickie Dastardly]

Hinged my bonnet and now looking at tidying up the engine bay, starting with getting the rocker cover done.

When removing the rocker cover is there anything I need to be particularly aware of? Do you remove the scuttle panel or is it left in place? Is the rocker and the plug cover refitted using instant gasket rather than a traditional gasket?

Any info from previous experience welcome.

Cheers
