350㏄ EW or 1930 Ⅼ-3 cylinder head

[yoshimasa negishi]

I am in the process of restoring a Douglas Ⅼ-3 in Japan.

I am looking for a 350㏄ EW or 1930 Ⅼ-3 cylinder head, front and rear pair.
My cylinder head is severely cracked and unusable.

The heads pictured are reference images.

Does anyone have used spares?

I have a pair of cylinder Heads from an A31 which I think would suit an L30.
