Sorry to hear that you had problems instalingl the new alum. valley cover. As I mentioned in my above post, installation problems are most likely to come up with most non blueprinted engines. It's not the fault of the new pan, it's the misalignment in most engine's geometry. The flexing stock steel pan can perfectly compensate in most cases.
Hope the elonguated bolt holes will do the trick for your engine. Do you have pics of your new alum. pan?
