I've been very suspect that the gooves do much. You are eliminating some of the squish areas that are designed to push the mixture toward the sparkplug and raising surface area of the combustion chamber.
I've never seen any honest dyno tests with emission tests on A-B comparisons without any other mods. I would also believe that if there is merit to them, that their size, depth, location, and angles would be extremely important and that merely hacking away with a dremel tool would never acheive the proper results. It would be like having a port grinder and guessing on how to modify your intake ports for more horsepower. Most of the time, you'd be making them worse then any improvements.
