Those ink marks your referring to ,were probably the manufacturer of the gasket material & possibly the thickness..

You are likely right and pan rail gaskets are like this also.

No luck so far on finding any but the hunt is on.

Getting closer.
The FP gaskets with "GM" and "Q" have 3/8" holes.
The ones with 5/16" holes have "GM" and "8".

This is obviously a very small database.

Timing cover gasket is same stuff.

Still looking for pan gaskets like this.

Looks kind of like Vellumoid gasket material. We used to die cut many of those gaskets a million years ago. All of the dies are long gone though. Might give those guys a call.

She thinks I am a bit wacko but this digging for stuff- info is fun.

Some must remember the pain with getting pan rails clean if you were the first person to remove a 69 396 oil pan.

Same on the silver valve cover gaskets.
They ended up in a jillion chunks everywhere.

Then you put the rubber ones in and of course leaked.

Wire wheel on the bench grinder is your friend...

Done this at least a thousand times beating warranty flat-rate in the dealership a million years ago.
