I have a book published by Peter Hunn titled "The Classic Outboard Motor Handbook" – copyright 2003. On page 91 there are several photos of the cylinder head installation on a 1958 Johnson 10hp. Very clearly in the photo you can see that the mechanic is applying, in liberal amounts , the silver, gooey, Permatex Anti-Seize compound to the crankcase head surface. The heading with the photo states: "a gasket sealing lubricant is applied to water jacket and cylinder assembly surfaces".
Is there any instance where this might be a good practice or was this possibly a mistake in staging the photo situation?
