I was watching a George Bryce video the other day. He hand finishes his ports. The reason the heads look the way they do off the machine is the companies don’t want to spend the money to hand finish them.
The Trick Flow heads I looked at had the best finish I’ve seen on a production based head. But I would still hand finish them. Also the finish is the way it is is because to make the finish any finer in the machine takes several more tool changes and more time in the mill.
It’s a money thing.
