940 Cylinder Head

Hi Chaps,

Is it possible, from casting numbers etc, to identify if a 12G940 head has unleaded valve seats or not?

The head in question is a big valve 940 which I believe, but can't be sure was from a Metro.

Cheers

John

If it is a factory 'big valve' then it is NOT 'unleaded' - but it doesn't really matter......
