Hello Mopar family. I have a 440 in my Dart and just changed the Valve Pan gaskets (Good quality Moroso gaskets, guaranteed not to leak……….. they leak) I am pretty sure the fault is the guy behind the wrench. I did some checking and it is recommended to tighten the covers in a cross pattern, and something like 40 in lbs of toroque (I have to verify that). Does anyone know the cross pattern for the 440. Thanks in advance Ron D
