Exactly Rick. I have the aftermarket cast fake "Porsche" valve covers. I use contact cement on both the gasket and valve cover, wait 10 minutes and stick them on.
Then I smear a very light coat of grease on the gasket. I usually get about 3 years and 3 valve adjustments before needing to replace.
I picked up 10-12 when the rubber-impregnated cork were available. They seem to compress a little less. My valve covers are bolt-on, no bails.
