I bought a cylinder head (with cam, valves, etc.) How can I tell if it is from S or not?

 

I wish I could help you, but I can't. Try posting this on roadfly.org Look for the MINI forums, then try the Sterling Parts Counter forum.

If you find out anything, tell us. Especially if there's a way to distinguish the JCW head externally.

PS Of course I trust car dealers. I trust everyone, just not the devil inside them!
