Rev limits are a function of valve springs and cam lift.

Horsepower is a different topic - our 2L turbo engines have the exhaust manifold integrated so there is a finite limit to how much exhaust can come out of the head. Depending on your math skills, some have calculated that you need to revert your engine to generation 1 heads found on some of the older Mondeo models in Europe somewhere around the 425 bhp mark, since those still use an external exhaust manifold. Not sure of what other valvetrain work is needed to get to that output.
