Boss Head Casting Numbers

I can't locate the thread we were discussing the casting numbers.
I finally dug them out of my core room.
On the underside of one intake port they have D1AE and a GA raised casting on the bottom of another port. On the top side of the heads there is what looks like a date code. OG22 Whatever that stands for. Didn't know if these would help any of you Boss racers. They appear to be in pretty good shape. The valves are all up high and they don't have any visual signs of distress. They appear to have all stock valves, springs and rockers. I will Vat and Mag them to make sure there are no problems.
