I just talked to someone this past weekend at West River Westies who was having issues with them leaking oil. 
The solution was taking a set of gaskets and glue them together. Then after their dry using a sealant to adhere them
to the valve cover. No problems now. If you could find a set 
of thicker gaskets you might be fine as is. 
I personally don't find the "bling" factor on these worth the
extra hassle. A better option would be to have a set of stock
ones powder coated in a different color.
