MG MGA - cylinder head casting


I have a cylinder head with the following casting number :12H1670 AF2
i think it,s a MG A head but I,m not sure..
It,s in a BMC carton box with the number 48G432
can anyone tell me something more about this head ?

Have a look at Barney Gaylord's extensive write-up:

hi steve ,

thanks for your replaid,

i have seen the info on that website before..
but this head has no "15" mark on top
and the date on this head is 31-1-68..
the shape of the chamber is like the MGA head but the volume is 43cc instead of the 39cc mentioned on the website..
