removing rocker cover damage all gaskets?

[da_foles]

Question
I have a leaky rocker cover gasket that needs replacing for roadworthy. I'm going to do it myself. Now can I just buy the outer gasket and replace it or should I get the full set? Will removing the rockercover lift the existing smaller gaskets in the middle? Help appreciated. Gen 3 st205 motor

it all comes as one set as you need to replace all in one go due to gaskets compressing over time.
