| Dear MGlers,
I need your experienced help in identifying a series`A' head.
        
Last May I bought this head for a series 'A' engine that said:
        159
        MOWOG
        12A185
        W90 
        (or 06M?)
I hope it's actually for a 1275cc engine, since that's what I have on my 
Midget.
So, now I looked these specs up in David Vizard's book, it said:
12A185: Intake: 1.4",   Exhaust: 1.156", was mounted on 'S' engines 
(e.g. Cooper), color: yellow.
I took a measurement and found:
        Intake: 1.175", Exhaust: 1", color: blue
What's wrong with this picture? I couldn't find any clues in the book, 
but maybe he was only mentioning the biggest possible valve sizes? That 
would be in a different chapter (but he repeats himself quite often 
anyway). 
I would be glad to see if anybody else can come up with more reliable 
data for this head (12A185).
There's supposedly a great book about Minis that has all the information,
but I don't have that. 
Cheers,
        Gus
