Original Pan, Intake, Valve Cover Gaskets

[Monte M.]

I found a box full of gaskets. I know the box is at least 28 years old. It is full of GM big block oil pan, intake, and valve cover gaskets.
Are these a find or are the new ones the same as these?
What is it I am looking for if they are different from the new ones?
Has the part number changed over the years?
I know the much older ones had a little tab that said "GM". Can anyone tell me if the big blocks had the same tabs and where they are?

Any help would be appreciated

Monte, send them to me to look at and I'll send back anything repro

How about if I just send you one set of each?

Monte, perfect!

So the answer is a bit more detailed, these also were kits for the tall deck blocks, generally the rubber parts are the same and most important. Intake sides are worth 2 cents as a repro so if these are the dark gray and have the supplier logo, good stuff!

Monte -- here's where the GM is on the tab, at least on sets with the locating "tits". I have a couple of sets of BB gaskets, circa 1969. Also have other pics of the markings on the intake manifold-to-head gaskets, but I'd have to search.
