Sorry guys, but it's a bit more involved than that because the wiring for the fuel injectors is built into the gasket. You have to be really careful tightening down the nuts that hold on the injector connectors because they're really easy to overtighten and damage the injector. Try tightening the cover bolts, cleaning the engine and driving it a few days to see if the leak reappears before you replace the gasket.
