12G940 (33) Cylinder Head.
HIF38 Carb
MG Metro heated inlet manifold
MG Polished Alloy rocker cover.
£300.00 ono Nuneaton, Warwks.

May split if interested in individual parts.

Hi, What is the 33 version of this head? I have not seen that version before.

The number is 133 which is in all probability the casting batch number or casting identifier.

If you look on 'e' bay at 940 heads you will see a variety of secondary numbers which though different do not indicate differences in the basic 940 head.

I'd always believed it was to identify 33mm Inlet size but that was a guess so happy to take advice from more knowledgeable members.

Here is the list of standard production heads:

The one that is missing from the list is the 12G1805 late Cooper S /1300 GT etc variation of the 940 head. 12G1805 is stamped on the head by the thermostat opening.

You can do the imperial to metric conversion :wink:

The numbers may be too small to read clearly - in that case save photo and enlarge.

I really don't want to ebay these parts (I'm not in the mood for the timewasters) so I'll give them another bump on here......
You're welcome to come and have a look and feel first if you wish and I'll happily talk sensible offers, but we all know the value of these parts.
Cheers.
