OK, I'll change it to Sigma.

Reading the wikipedia pages on the Duratec and the Sigma, I thought it was the other way around--Sigma was a family and Duratec was more specific. It's confusing.

I think it's confusing too. However, in the GEN3 engine installation manual from SCCA Enterprises, the introductory page starts with a section called "Intro to the Ford Sigma 1.6 -liter GEN3 engine", so we'll assume that's the authority.

From the Sigma page it looks to me like this is the one : 1.6 Duratec Ti-VCT (2012-)
Then down below it states that the SCCA Spec Racer Ford uses the "1.6L Sigma" so clearly Ford marketing didn't burn the midnight oil on the naming conventions. :)
