Fabrik8 makes a good point.
To elaborate some....
That can restrict the exhaust flow. What does that mean? Well, it can mean less top end power. This can be especially true if you're running a turbo near the top of it's flow range, or using a high-revving N/A setup.
Specifically, if you look at what Crane considers a turbo-grind, that's almost exactly what you'll find. A stock (or slightly more agressive than stock) exhaust cam, with a much more agressive intake. As a general rule, on a Turbo setup, that allows more intake air, which then creates a higher exhaust velocity. It can spool a turbo faster, but comes with the possibility that it can also hurt flow on the top-end.

For a naturally aspirated motor, it's allowing more air on the intake side, but it's leaving at a higher velocity. This means if there's any flaws in the exhaust system, they'll be much more evident, and you may actually lose power. If the exhasut is designed perfectly, it may enhance power even more.... On the Intake side, having it open longer could cause the air to stall. This would be especially true of the intake/induction system were unable to provide enough air to sustain the motor..... Depends on how well everything is optimized....
WAY too many vairables in that scenario to predict what it will do.

Now, more specific, on a Honda engine, with I/H/E, and the ability to tune, yes, it should make more power than stock GSR cams. It should spool faster for a turbo setup than Stock GSR or ITR cams. It may not make the peak #'s a full set of ITR cams will, but will likely enhance mid-range slightly.
