I remember reading something about this before. Most stock 440's have this
problem due to the closeness of the exhaust manifold, which just burns up
the gaskets in time. I believe the solution was a small heat shield that
bolted on with the valve cover bolts.
You could probably make one yourself, or if there is a part number out there
someone knows of, could they volunteer the information?
It may even be a motor home or RV part.
