Definition of Head Porting and Polishing
Head porting and polishing is an art which takes patience, knowledge
and know how to accomplish. A cylinder head is an object which
is one main part on an automotive engine. It supplies the engines
airflow/fuel mixture into the engines combustion chamber and cylinders
were the power is then made. The more air and fuel the engine
receives, in return the engine makes more power. Porting and polishing
of the cylinder heads intake and exhaust runners (the tunnels
inside the cylinder head which contain the majority of area to
be ported), bowl area (the section under the valve seat at the
end of the intake runner and at the beginning of the exhaust runner),
short turn area (the turn at the end of the intake runner were
it meets the bowl and valve seat and visa versa with the exhaust
side) and combustion chamber (The area were the air and fuel are
swirled together, the air and fuel is compressed, then a burn
takes place there as well) are the main keys in cylinder head
power. A factory cylinder head off a common engine is cast, cleaned,
assembled with valves, springs, seals and locks then is assembled
onto the automobiles engine. I take the factory or high performance
"Hop Up" head and port and polish it for maximum power.
A gasoline engine is just like an air pump in a way that it takes
air in and sends air out. The more (CFM) air/fuel mixture you
can squeeze into the engine, the more power it will make. This
is one of the many ways to make big power out of the automotive/gasoline
engine.
