If you’re looking to get the most out of your engine, porting and polishing your cylinder heads can be a great way to achieve better performance. But what exactly does it mean to “port and polish” your cylinder heads, and what benefits can you expect to see from this modification?
In this article, we’ll take a closer look at ported and polished cylinder heads, including what they are, how they work, and what benefits they can provide. We’ll also answer some frequently asked questions to help you determine if this modification is right for you.
The cylinder head is an integral part of an engine’s combustion chamber. It sits on top of the engine block and contains the valves, valve springs, and other components necessary for the engine to intake and exhaust air and fuel. The ports in the cylinder head allow for the intake of air and fuel into the combustion chamber and the exhaust of spent gases out of the engine.
Porting and polishing the cylinder heads involves removing material from the ports to improve the flow of air and fuel into the combustion chamber and the flow of spent gases out of the engine. This is typically done using a variety of tools, including die grinders, carbide burrs, and sanding rolls. The goal is to create a smoother, more streamlined path for the air and fuel to travel through the engine, which can result in better performance and efficiency.
The process of porting and polishing is a bit more complex than simply grinding away metal from the ports. The key to a successful port and polish job is to carefully shape and contour the ports to maximize airflow while minimizing turbulence.
The first step in the process is to remove any casting marks or rough edges from the ports. This is typically done using a die grinder or carbide burr to carefully smooth out the surface of the port. From there, the port is reshaped to improve airflow. This may involve widening or deepening the port, changing the angle of the walls, or adding a radius to the corners to reduce turbulence.
Once the port has been shaped, it’s polished to create a smooth, mirror-like finish. This is typically done using a series of sanding rolls or polishing wheels, starting with a coarse grit and working up to a fine grit to achieve the desired level of smoothness.
