    I came into a pile of valve shims that are about 25mm in diameter-represented as fitting "a Ferrari". Any idea which one they could be for? The ones on my 348 are approximately 28mm diameter.

    I don't know the exact size off hand but the 2 valves are the same as Fiat, Lancia, and Volvo

    And the 4 valves are smaller than the 2 valves, don't have the size, I have to go measure mine.

    Some Maser were about that size in the 80s I think.
