If your talking about the valve cover seal, then no I wouldn't put silicone on it. I have had mine off several times and reused the rubber gasket with no silicone and have never had a leak.

No sealant. Especially no silicone sealant. You'll actually encourage a leak using that. As long as the gasket stays in place well enough to go into position properly, use nothing else.
