Head porting - please explain?

Can someone give me a rundown of the process of head porting, and what exactly you gain from it?

Re: Head porting - please explain?

In a nutshell it removes all the casting dags etc by gently opening up the ports , floor roof short turn etc for an increase in flow & better swirl effect, inwhich gives alot better filling & exhaust capabillites upping horsepower.

Re: Head porting - please explain?

ah k, thanks for the rundown. by the sounds of it, it's not really worth doing until you've got some pretty serious upgrades in place already.

Yeah, not much point unless you've got a full exhaust, extractors and a cam.

Re: Head porting - please explain?

I think you will find that its easier to do now whilst the heads is off rather than later., Atleast then its just a matter of upgrading the exhaust system...
The next best thing than buying an aftermarket head.

Mine was fully reco'd and ported at Mick Webb's SVO in Ringwood for $800. Other places like JMM do it too.

Re: Head porting - please explain?

also what you port a head, you put bearing blue on the intake and exhaust sides of the head and bolt the manifolds to the head then take them off again. this will show any places where the manifold and head dont line up properly and cause a slight protrusion and slightly restrict the flow. then you use a die grinder to open the ports up to get rid of the protrusions on the head and the manifolds.

also you dont get rid of all the casting dags on the intake port because they help cause the swirl effect.
