Keith - What plant are you asking about since different plants often did things differently. Assembly manual only showed what Ford engineers and others thought it should be done - when the page was printed. Might have been different the day before or a week /month later - the reason the pages were printed and updated.
With a plant identified we can focus better. Also while we're at it are you interested in 6 cylinder through 390's, all V8's or something more specific?
