It’s not just the port work alone that creates spectacular cylinder head performance. The most critical areas of a cylinder head are those which pass the most air at the highest speed and for the longest duration. Your bowl area, the valve job, the throat diameter, and combustion chamber are all crucial parts.
The complexity of cylinder head set up and flow bench testing comes in the form of math, aerodynamics, thermodynamics, and the physics it takes to design the correct port and manifold design for a particular engine combination. These processes take years to master.
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.
There’s a million ways to alter cylinder heads for better power, so we spoke with a few cylinder head manufacturers about their LS offerings in the market, why LS heads are so hungry for horsepower and ways you can maximize their efficiency and power potential.
CNC block machining centers and CNC cylinder hones are some of the most popular machines today. These machines can increase productivity in the shop significantly.
In general, the most critical areas when porting a cylinder head are those which pass the most air at the highest speed and for the longest duration.
