no the street version has hemi heads on it, that is what made the engine. To satisfy the homologation rules Ford had to put out street units to run the engine. unless I am confused about what a hemi head is, the duratec has hemi heads also, right? a hemi head has the spark plug in the center top of the camber
the only difference in the cars was the early cars with the T code engine had nascar parts in them. The later S code engines had just normal parts in them. Might have the codes backwards but you get the idea
