NO, do NOT remove the spark plug washers on drool tube heads!!

Tyler, there's nothing wrong with guessing and assuming based on what you think you understand. The problem comes when you get on the internet and holler your guesses and assumptions in BIG LOUD ALL CAPS, and gloat about how right you are and how wrong and stupid everyone else is, and how thorough a job you did checking Chrysler's publications.

See here for the correct info as published by Chrysler in TSBs that are not difficult to find.

Yes, the Champion N14Y came with a washer, which was used in some of the many other applications for this spark plug. Here's a page from the 1970 Dodge FSM. The same language is in the '63, '64, '65, '66, '67, '68, '69, '71, '72, '73, and '74 FSMs, and that's the whole year range of \6 heads for which the plugs are to be installed without ring washers.
