I found this patent awhile back, I think it's from the 70's or 80's, but the inventor claims it reduces emissions, lowers fuel consumption, and increases power due to complete mixing of the air & fuel.

The edges could be rounded more so they don't create hotspots. Or even convoluted.

I cut grooves into my head to reduce compression a little as im running a bunch of boost with higher than stock compression. if you cut into your head, you should cc the chambers
