ported heads

[silverford96]

what are ported heads, intakes, and that stuff, what is it. what does it do?

what does it mean to P&P your heads. can somebody explain this stuff to me?

ported means that the runners are opened wider to allow more air volume
polished means the runners are smoothed to have no turbulance in the air stream.

so if you port and polish, you allow more air into the engine and out of the engine while allowing the air to flow more effeciently, thus making more hp.

[Mjcorn23]

The general way to make horsepower is by getting more air and fuel into the engine and by widening the air flow through the intake and heads and then smoothing them out to get rid of all the obstruction gives your engine more air.
