If the gasket has been in place for 3 years regardless of mileage, I personally would replace it.

On the other hand, it is a relatively simple matter to replace the gasket if it shows a leak. Also, I would try the VR gasket. Some work well, some don't. I never use any sort of gasket cement. It is a scab that is painful to pull off later. If something is needed to keep the gasket in place while installing, I recommend a coating of simple assembly grease.

Your call; easy to recover from if it doesn't go as you dream it should. One more tip; I remove the cruise control actuator. Three small bolts and it offers more maneuvering room for setting the valve cover.
