Jeff N and Martin have done that on Jeff's car with some success.
It's been out of commission for so long though that it's hard to really compare it accurately... it's not so much better that it's like there's a extra litre of displacement now, and I've only had a hour of driving on it thus far.
Was it worth the $400 for the cam? Yes, just about. It's not a huge increase but kind of like installing a chip - fills in the dead spots and makes a bit more responsive all around.
