1.15" x 3.56" exhaust valves for 1275cc heads.
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 it 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!
12G1316 (Smog-Type), all variations of the 12G940, and the latest CAM head castings all use the 3.56" long valves.

Do I need to do a Valve Job on My Classic Mini?
Created: April 25, 2014
Most motors will go at least 80,000 miles before "needing a valve job"! But what are the signs? How do I determine if I really need it? Do I do it myself or pay a local machine shop.

Call them cotters, collets or keepers, these little items are often overlooked during a head rebuild. If yours are worn and need to be replaced, make sure you order the right ones. Minis used three different versions over the years.
