I'm interested in getting a porting job done on the bigport head on my 4AGTE. Nothing crazy, but a good cleanup of casting dags & any other flow restrictions, rather than enlarging the ports particularly.
Who have you guys used for head porting? I'd prefer to send the head to someone that has had positive results with these heads in the past. Is there any particular areas of the ports that should receive attention? I have considered doing it myself also....
