Question regarding 1956 Intake Manifold Gaskets

[Gordon A.]

Do the correct manifold intake gaskets have "GM" stamped on each of the square tabs? I have a set of gaskets that have the GM on only one tab. Is there a source for a correct gasket if these are not so?

I believe that the "GM" embossment was on only ONE of the tabs on each end seal.

"GM" is on both end Gaskets and so far I have found 7 different kinds of "GM"

It's on both end seals but, as far as I know, not on each tab of each seal. I interpreted the original question to involve whether it was on each tab.

Why seven different configurations of the logo? Well, there were probably at least that many molds used for each supplier of the seals and there was probably more than one supplier. So, I expect there may be a lot more than sevem variations.
