Description

As it is possible, even common, to swap one head for another on 1275 engines, it is quite easy to become confused, or worse yet, confuse the parts-guy when it is time to order new valves! 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 3.44" & 3.56") three different keepers, (wide, narrow, and three-groove) and many different head diameters! These valves are 35.6mm or 1,401" DIAMETER and were fitted in the MG metro. They are a super quality road valve and used by Minispares in their gas flowed road heads.These are A plus triple collet groove types and are the next size up to all the standard 1275cc inlet valves. latest CAM head castings all use the these 3.56" long valves.
