At least in '39 - '40, the center water passage was different between the Ford and Mercury castings. Ford had a trapezoid shaped passage while Mercury had a round passage.

This is from Best for copper or graphtite gaskets.

Install using using a spray-on sealant like K & W Copper Coat or Permatex Copper Spray-A-Gasket. Always re-torque, no short-cuts.
