Alloy cylinder head ID
« on: 14.06. 2017 17:04 »
I can find no cast part numbers on my head, however the head is stamped thus: 59B11KJ this stamped number is set vertically on the rear of the near side where the rocker cover stud passes through. Does anyone have any idea what head it is?

Hi,
I believe that is some kind of date code? but I have never seen it deciphered?
Usually the part number is on the underside of the inlet manifold

John, thanks for that, I will get my mirror out tomorrow and have a look to see if I can find a cast on number.
