I am hoping Ted can respond to this. I was cleaning up some parts and noticed that there are three distinctively different cup washers that retain the intake manifold to the heads. I notice that one is totally dome shaped while another seems to be of less material, and has a flatter area where the stud goes through the part. The third variation is about halfway between the two. There may be more. Are any of these significant? Is there a certain year when they were changed? Thanks

The intake manifold clamps (aka turtles) went through several variations during the years of production for the Ford Y. I find no fewer than six different styles not including what was made by the aftermarket. For the 1963 and 1964 Ford pickups and trucks, they were cast iron. For the years prior to this for both the cars and trucks, they were stamped steel and depending upon the year, the styles or overall appearance changed. Here’s the link to an older thread discussing some of those variations.

Interesting. Although there are many different styles, are they all application-specific as far as fitment is concerned? Which is correct for the ECZ-B intake? Can the stamped steel "turtles" be used with the Mummert aluminum intake? If not, does John include aluminum turtles with the manifold?
