unexpected stamping on driver side 782 head

[chromguy]

I bought two 2.5 NA engines today, An 89 and 90. One head has several unexpect markings, what do they mean?

I don't know, but it looks like that head has been rebuilt. I would suspect they were added at that time.

ETA: The CD looks factory and I believe it means cross drilled.

Reman head, you can see the heat disk they install to tell if the part has been overheated.

Excellent, thank you gentlemen!!
