PORTING AND POLISHING!!! People have been doing since car’s have been around. This was more of a thing back in the 60’s and 70’s where you would see this happening on carbureted engines. Even though cars nowadays are fuel injected, you will still see a performance gain by doing this process to your aluminum / steel cylinder heads / manifolds.

Cylinder head porting refers to the process of modifying the intake and exhaust ports of an internal combustion engine to improve the quality and quantity of the air flow. Cylinder heads, as manufactured, are usually suboptimal due to design and manufacturing constraints. Porting the heads provides the finely detailed attention required to bring the engine to the highest level of efficiency. More than any other single factor, the porting process is responsible for the high power output of modern engines.

Cylinder head polishing refers addressing the imperfections in the casting or during the porting procedure. The polishing stage is where you will get the last 10% of power and efficiency. It levels out the high spots to make a more uniform and consistent finish. By doing that, it allows the air to flow much faster with less resistance through the port. Depending on your fuel system, you will want to either polish to a brushed finish by stopping the refining stage at 120 grit, or continue to to a pull mirror polish finish.
