I am proposing that texturing the intake ports creates benefits, and have some data to support that claim. The chosen vehicle is screw threads. Dana44 from another forum uses the scallops caused by a chattering carbide bit as his vehicle and claims very positive results.
If other head porters were to take this subject seriously enough to devise their own tests, and perhaps their own frorm of texturing, this whole "port texturing" theory could be refined into very predictable data. Sharing this info puts into the hands of customers better products, regardless of whom the porter is. As a head porter, I'm sharing this info with hopes of getting back testing data from other head porters so that my own process can be improved.
If this is as significant as I think, then it should be shared. It is a tuning tool and not a means to an end (my thoughts on the Somender Grooves as well). So what I'm doing is giving away one of my trade secrets in hopes that the process can be refined by the hands and minds of others and we all can benefit.

haven’t tried this but I have been following this for some time now.
What he explained to me was he puts threads inside the ports, when
fuel falls out of suspension the grooves collect the liquid , it is vaporized
from the heat of the intake and returned into the flow.
