    clean valvecover and apply silicone to valvecover gluing cover and gasket .
    let dry by puting vavecover on flat surface and letting the weight make a good pre-load to stick
    don't forget to make bolt holes line up-

    You could go ether way The blue stuff is ok untill you go to pull off the valve cover, I like the rubber gasket myself. But what it comes down to is whatever keeps the cover from leaking is good to go.

    Thanks for your responses, I replaced the heads a little while ago and one of the valve covers leaks and I only wanna pull the injector lines off once.

    After you clean the cover up you might want to wipe it down with alcohol to get all of the oil off before you apply the sealer. Seems to help and lets you know about all of those little cuts on your hands at the same time!
