I've got a C.A.W. valve cover myself. I picked it up at a swap meet in Oklahoma some years back. My next store neighbor lived in Denver for a number of years and tells me that part of town is kind of a warehouse-industrial area. Tom Langdon also has one of these valve covers, or at least, had one. I know of two other people that have one also. One of those people is Chris Lieb and he speculates that perhaps a trucking firm had the covers made up to put on their fleet of trucks. I'd say a pretty good guess, but who knows why. Maybe tappet noise?
