valve cover gaskets

[leenigen]

I have a '94 with a 6.5NA that's leaking oil badly from the valve cover gaskets. At first it was a mild annoyance but it seems to have gotten worse. In order to change the gaskets it looks like I'll have to remove the injector lines. What problems could that cause me? I'm worried about restarting the engine - not to mention broken injector lines. How hard is it and what's the process of restarting the truck when the injector pump has essentially been drained of fuel?
