Help with casting numbers

Hello gang

A few weeks ago I posted a question on casting number and I see that my Block is for a 66 However I just finished cleaning it and see additional casting numbers. Please help with decoding

Rear Casting numbers H22 Letter C under it. Number 174 under 174 number 852 Center top ledge:
Upper Center ledge number 1 and under it C286

In front of block 174 under it numbers 362 "OX" ?

5 GM 3858174 Bottom Front Lower right Letters "HB"

Thanks
Bill

Those are foundry core segment identifiers; the only numbers that matter are the casting number on the driver's side rear flange and the casting date on the other side.
