Does dimpling intake ports work?

A fwiw, Jim McFarland published quite a bit in Circle Track magazine including tech material on dimpling.

"Of course, and we sometime get a little push-back on this notion, there's always the approach whereby the surface texture of the inlet track (manifold runners, cylinder head ports and combustion space (chambers and piston crowns) can be roughened (or dimpled) to create little eddys or Von Karman rings that energize flow surface boundary layers and improve fuel atomization. In this regard, and as a point of interest, I've heard from some engine builders that have given this approach a chance and were pleased by the results. Might give it some thought. It's not magic."
