Racing Beat just does it around the spark plug area. If it's overdone, it weakens the structure. How much is too much? I don't know. I considered it for my recent 4 port 13B, but decided against it since I've never seen it in real life and won't be racing the engine.

Would there be a point to doing it anywhere aside from near the spark plugs? Perhaps near the intake and top of the rotor housing to cool it through the intake phase? Or would that actually heat up the incoming fuel/air mixture?
What about near the bottom and exhaust ports? I suppose no gains there, as you want all the expansion you can get there. and once the burned mixture is gone, there's no need or way to cool it.

Other than the plug area and maybe the exhaust area you would be better off slowing down your water pump to slow down the water a little. I made a bigger water pump pully after I installed a smaller crank pully.(No room with a stock crank pully) this helped a lot of things on the racecar.
