what does porting engine heads do
Port/polish work is a relatively simple process that is performed on the engineâs cylinder head. First, the intake and/or exhaust inlets (ports) on the cylinder head are enlarged using a grinding or cutting tool. This extra room helps the engine to draw extra air into and out of the cylinders, mixing it with more fuel which means more power. The enlargement of the inlets is what is referred to as âportingâ.
