Replacing Grouphead Gaskets Astra Mega IIc Espresso Machine

This demos how I replace the grouphead gaskets on an Astra 2-group espresso machine.
The other way I thought of but have not yet tried is to use a screw turned into the rubber gasket and a plier or a pry tool to pull the screw along with the gasket out.
Tools used:
Flat screwdriver
Rubber faced hammer
Dremel and 3 different style brushes
Lubri-Film NSF water-based lubricant on gaskets
