We did a 2005 Corvette a long time ago and left everything else the same in the car (already had headers on it) and I want to say it gained 27 rwhp and about 10 lbft torque.
Interestingly though it did loose some low end torque below 2500 RPM (I think 10-15).
Decent upgrade though, for sure you would see more power by doing that with a larger cam to take advantage of the bigger runners in the heads.
