These numbers are CAST onto the head, under rocker cover:

Cooper 997 head is 12G202 (also Morris 1100)
Cooper 998 head is 12G295 (early were 12G206, pretty much the same)
Morris 1100S head is 12G940- some stamped 12G938 near t'stat- 33 mm inlets
Oz Cooper S MK2 head is 12G940- most stamped 12G1805 near t'stat- 35.6 inlets
1275LS head is 12G1316- 33mm inlets- `smog' head
