Our race valves are produced in EN214N stainless steel and require Manganese/Silicon bronze alloy valve guides. They are stellite tipped and have the triple collet groove and current valve head shapes. These valves are heat treated to eradicate wear from unleaded petrol.
As it is possible, even common, to swap one head for another on 1275 engines, be aware that if the head has been worked on previously, 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.

As an engine wears, the clearance between the valve stem and guide increases; as this gets beyond tolerances the car will tend to smoke under deceleration (when you take your foot off the throttle). Good valve stem seals will allow for greater wear b...
New colour, PB104 bronze guides.Although Silicon bronze valve guides were used for their extremely good wear values, they were very hard and not user friendly when fitting. These valve guides are recommended when using all EN21 4N stainless steel val...
when removing the head for a decoke or changing valves/springs you will require this tool to release the collets holding the valves in place.
Genuine Mini Spares valve stem oil seal manufactured with original Dupont Viton, as fitted to the twin points engines, are the best material and seal you can use and although expensive are the best to date in stopping the engine smoking.
