MINI & MOKE 1275 EXHAUST VALVE – 1.220″ (OVERSIZE) [C-AEG107]

 Our race valves are produced in EN214N steel and are stellite tipped and use the later narrow, single collet groove and current valve head shapes.

• Length220″ (31mm) diameter x 3.57 exhaust valve.
• These valves are plasma heat treated to eradicate wear from unleaded petrol and can be used with our 12G1963 or C-AJJ4037 guides.
• As it is possible, even common, to swap one head for another on 1275 engines, it is quite easy to become confused,it may have oversize valves; it may have undersize if seats have been installed.
• Unless you are 100% sure what is in your cylinder head, it is a good idea to remove a valve for accurate measurement.
• There are two lengths used (nominally 3.52″ & 3.57″) three different keepers, (wide, narrow, and three-groove) and many different head diameters! Note that 12G1316 (Smog-Type), all variations of the 12G940, and the latest CAM head castings all use the following 3.57″ long valves.
• Alternative/old part number was 12G1322.
