this is the first two port s of a A12 head being ported the intake port is finished even thoug it looks rough i have heard that it is a better way to have them as it atomise and breaks up the fuel befor it enters the combustion chamber but the exhaust is still to be smoothed

 Re: porting
How did this porting go? did the rough areas help with Fuel atomisation?
Im interested in going higher on the roof and leaving the base height alone.
