Do the 2007 mazda miata cars have a problem with blown head gaskets?

No, I am sure some of them have suffered a blown head gasket. But I don't think enough to say the entire year has the problem. At least not from the factory.
The three most common problems had to do with the treads on the fuel cap, valve tappet noise and leaking slave cylinder.
