I've replaced but only one, at the owner's request. Mostly they may stay in place on the valve cover, but if they don't, I remove and clean the groove and the mating ridge on the gasket. Final clean with isopropanol. Then I sparingly use RTV in the groove, install the gasket, press in, let sit for an hour before putting it back on. Clean off any stray RTV on the inside of course.
There are other "adhesives" for that job, but RTV works.
It helps to have a helper keep stuff out of the way while you reinstall the valve cover... don't want to contact anything (if possible) that will knock the gasket out of place... worst spot is that coolant hose, left front, gotta push on it forward before you can get the cover down. Then check the side half moons are seated properly.
Keep yer stick on the ice....
