hey munz
yer this is what my tuner talked me in to going lol. the epa told me that to pass the cam needs the exhaust inlet to close as some other input opens as they cant close at the same time as fuel will shoot out the exhaust something like that
that stuff gos over my head thats from the epa in nsw head inspector where the car will be getting engineered
had the heads done like you said from other thread as well plus lifters and full cam kit
