I have a box of the 30mm valves shims.
But my engine is an early one and uses the under cup shims.
I have many different sizes of these but for other engines, mostly Japanese motorbikes. Can anyone tell me the diameter of the smaller shims.
Thanks

Re: Valve shims
8 mm. Alfa Romeo 750 series also used 8 mm but I don't have any 750 series cars anymore to compare Alfa to Fiat/Ferrari shims to see if they are identical. I wish the Dino used 9 mm shims, as I have plenty of those and Alfas to go with them.

Re: Valve shims
Wow, thanks for the info. That would barely cover the valve stem. The smallest I have is 10 mm

Re: Valve shims
8.04 mm inside diameter, same as the diameter as the 8 mm valve shaft. It is a snug fit. It is a cap, not a flat shim. External diameter is 10.2 to 10.6 mm on what I have in spares.

Re: Valve shims
Thanks Ben
Exactly what I needed to know. I am used to flat shims like the later engines used.
