Default What Head Gaskets Do I Have???

I just bought a set of heads and the seller threw in new GM head bolts and gaskets. They are part # 12558809 and 12558810. Are these the old style or the new style?

They are the old gaskets, but will work just fine. The new gaskets only have one part number. Cant remember it off the top of my head.
