Valve head cover - very hard to remove

[Overknasten]

I am still trying to check the valve adjustment on my Fulvia 1.3.
I tried last week but the head cover was completely stuck. I guess the old rubber gasket is adhering strongly to the engine suface.
Any good advice before I try more "brutal" ways. I am thinking of running the engine for a while and then give it another try?
Any other good advice or experience with this operation?
(I know I must wait untill it is cooled down before I do the adjustment)
I found the torque for the bolts in the repair manual - app. 12Nm

You should use carefull a rubber mallet.
