HOWDY FOLKS. $250 for Zeds (both heads), $150 for 4's. Just offering up a skill that I acquired over the years of playing with different forms of machinery. I have performed this with lots of success on rotaries, 4's, 6's and V8's and is a job worth doing if the heads are off for repairs. This job takes 4-5 days to complete once I have the head. Porting of the Zeds is more of a polshing and deburring process and port macthing with the manifolds for good interupted flow. A good modification for NA power improvements if combined with other mods (extractors and intake). Machining of heads and valves is best done after porting has been completed. I can be contacted on 02 4782 3126 or PMed on the forum for questions. PS. Getting the heads OFF and ON your car is your responsability, but if they are off for another reason let me know!. MattB
