Hello, I'm heading out tomorrow to a "salvage yard" to find valve covers for my 76 440, as mine are horribly disfigured from washers (I took off 25 of them) and overtightening by the previous owner. Since I know that finding a car with a 440 still in it is unlikely, from what other engines will they fit? Will the VC's from a 400 or 360 fit? James
