What is Porting Polishing? An art or science? People like
Jocko Johnson built businesses like Jocko's Porting Service if they knew what they were doing. It's a balancing act between flow and velocity.
Consider
Extrude Honing. It can offer improvement over and above an already ported and polished intake/head/exhaust.

How the Process Works
A plastic, abrasive-laden polymer media is pushed through a part, such as an intake or exhaust manifold, clamped to the processing machine. The media, sands away unwanted material, stress risers and burrs from the internal passage ways creating a smooth, polished surface. For most applications, the flow of the abrasive media is extruded in the same direction as the normal flow of the engine’s fuel and exhaust gasses.
Results
The Abrasive Flow Machining process creates obstruction free passage ways that allow air, fuel, and gasses to pass more quickly through the engine components to maximize flow velocity. The result is an engine that produces a faster, cleaner burn and more power output. The process routinely delivers increases that can exceed 30 percent on aluminum intake manifolds and 25 percent on cylinder heads not to mention a cleaner burning, more fuel-efficient engine.
