12G940 PORTED Cylinder Head. This cylinder head has been in my possession for many years from way back in my racing mini days. My wife is fed up with it all. I have removed the valves and given them a light grinding in and fitted new stem seals to freshen it up. It is a nine stud, double valve spring 12g940 with 29mm exhaust and 33mm inlet valves. Ideal for fast road use. The threads all look good and there are no visible cracks. By pass hose is good. 12G938S stamped near thermostat housing. As with these very old castings from the day, its impossible for me to give any guarantee with it, Im sure anyone would appreciate that. I can only be as honest as I can with my description. It would have been bought by me for one of my minis back in the 1980s but never used. A very good looking head. As you an see from the pictures, Ive tried to get as many different angles as I can.
