Some here are suggesting a spray-gasket(on both sides of the gasket)?? FINE-if you never want to take it apart. But if you ever have to ... it will be a mess. You will be scraping gasket material until the cows-come-home.
IMO .. you want to do ONE-side of a gasket and then OIL the other side ... that works great. You do NOT have to buy new gaskets each time something comes apart
REMEMBER .... the rocker-covers ONLY require INCH-pounds of torque. Do NOT overtighten. It will SQUISH the gasket and will WARP the stamped-steel rocker/valve cover.
