I think I would just buy a new plastic valve cover instead. They tend to crack over time. A new VC with VCG runs around $400. I think when you order the new VC it comes with the gasket - but ask your parts specialist. I know that's a lot... but its the only way to really repair an oil leak from the VC area.
Here are some pics of cracked N54 valve covers from fellow 1Addicts....
