What he said, just past snug. Overtightening them will actually cause a leak, but I think if you add some hylomar or even RTV and don't overtighten, they may seep a little but they won't leak real nasty.
Sam, I have a new in the bag OEM valve cover gasket I'll bring along to the rally if you want it. We can even help you put it in. Only takes an hour maybe.
As long as I'm getting dirty working on somebody else's instead of mine, I'll be happy.
