I've got the 964 grind cams also. I recently dyno'd the car and the results were 258 hp rear wheels assuming 15% loss SAE corrected at 248 hp. This is with a couple of other modifications so I have no idea what the gain was with just the cams. I am very happy with them and need one more upgrade to a SW chip to get the best out of the changes. Plus the sound at idle is really cool.
