Trickflow 240 clean up

I have thought about that very thing before. The CNC finish is "rough" in comparison to the hand ported finish. But remember, it's not the finish, it's the SHAPE of the port that counts. I'll say this.......if smoothing out the CNC marks showed benefit, that would be included as the last step in CNC porting, OR people would be flocking to have it done after CNC porting. They're not.
