The Ford Performance cams for the EBM are the same cams that come in the FoRS. Honestly, they only made a few hp over the baseline on a car with a ported head, bigger turbo, etc. Even though they're a low cost item, the amount of time, effort, and resources to install them wouldn't provide a sufficient return.
If you seriously want cams, I'd recommend waiting till an aftermarket company releases something more robust. It's also worth nothing that the factory valve springs and related components would need to be upgraded as well. The factory springs are relatively weak and would take a huge crap with upgraded cams.
