To continue with the overspray slant to this thread, here's a photo taken in late '62. The same molded mask was employed back then at Tonawanda as well.
Paint can be seen on the intake side of the one head as well. Also note that the one valve cover never received its decals which is another example that they all weren't done the same way.
Here's another unmolested '62 intake which shows a "little" paint on the sides.
If the same technique was used in later years, I see no reason to doubt Rick's observations. If these motors were painted in a minute or less by various workers I would expect lots of variation in the results.
