CAM Cover Removal

[Curdster]

OK I am embarrassed to ask this question but...
I need to remove the Cam Cover. All hex bolts are out. Do I need to remove the plugs, and as per the picture do I need to remove the 4 X M10 nuts, or are they holding something underneath onto the Cam Cover.
It looks like the gasket is sealant and not a true gasket. Any recommendations for sealant when I re-fit.

When reselling, I think I used high temp silicon, the loctite stuff and no more than the width of a matchstick around the edge.

And yes you do need to remove the 10mm nuts, and no you can leave the plugs in, that way, when you spin the 10mm nuts off and drop one, it doesn't go down a plug-hole and into the engine, .

High temp RTV sealant for re-fitting. And make sure you don't trap any of the wiring when you put it back on.
