1.311" (33.3mm) dia x 3.57 long intake valve.
Our race valves are produced in EN214N steel and require Manganese/Silicon bronze alloy valve guides. They are stellite tipped and use the later narrow, single collet groove and current valve head shapes.
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 3.52" & 3.57") three different keepers, (wide, narrow, and three-groove) and many different head diameters! These valves are in stock at Mini Mania!
Note that 12G1316 (Smog-Type), all variations of the 12G940, and the latest CAM head castings all use the following 3.57" long valves.

New competition valve cotter, these are precision CNC machined from 4340 and heat treated to a better spec than EN24T and claimed to be stronger in fatigue life. This is for one pair (two halves) - 8 are needed for one A-Series head.
These are made to RACE specification as the only current type available are not adequate for performance heads or valves. We tried everything else available and decided to go one better in quality and fitment, do not take a risk--buy the best available on this part.
All the early heads used the 2A11 cotters, noted by the wide slot in the valve. Current production race quality valves and most aftermarket valves, use the 88G549 keeper with a single narrow groove. Valve stems with 3 grooves on some A-Plus heads, use CAM6795 keepers. Order the correct cotters to go with the valves you will be using. Two halves equal one cotter for one valve, order 8 for 1 complete cylinder head.

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 3.52" & 3.57") three different keepers, (wide, narrow, and three-groove) and many different head diameters! These valves are in stock at Mini Mania!
Note that 12G1316 (Smog-Type), all variations of the 12G940, and the latest CAM head castings all use the following 3.57" long valves.

The engine build I recently covered in previous Mini Magazine issues developed into a bit of an ongoing 'project'. During a discourse with the editorial staff at Mini Mag, it was decided the build feature presented an ideal opportunity to demonstrate just exactly what such an engine build is capable of in days where it's generally believed you have to have an all-singing, all-dancing 1380cc engine to have an enjoyable road burner - leaving those with very limited budgets a little depressed.

Many moons ago, the standard performance valve shape was the then-ubiquitous 'penny-on-a-stick' profile. For the very good and simple reason it minimised airflow obstruction by having the least amount of material in the way. Very plausible, and a design that many have stayed with to this day
