Conti Tubulars: Removable Valve Cores?

Anyone know whether Conti tubulars (Competitions) come with removable valve cores? I know the Tufos do, but I’m thinking about getting some Conti Comps and would like to use the type of valve extender that requires a removable core.

If so, what tool did you use to extract the valve core from the Contis?

that’s one of the nice thngs about tubbies

and you can use the same tool
