I have just taken the valve cover off my mini engine and it has a 940 head on, do the other casting numbers around the head mean anything about valve sizes, The block has an engine code 12A2AG01, Rob

It's just an ordinary 1275 engine. So 33 and 29 mm - unless someone has fitted a better head at some point of course.

The engine is out of one of those later coopers but i would be amazed if it had any head mods, thanks.
