Hello, I'm about to start a weekend business...I'm going to college and have taken a porting and polishing course...This is the second course I take for this type of work...my question is this, I know turbo and non turbo heads are identical except for the cams exhaust cams. 90 intake cams are identical on all cars but not the exhaust cams...and they differ in 91 and up I believe...So I was wondering...do the NON turbo heads have accomodations for the oil feed line? Is there a plug that can be removed and used? I can find hundreds of non turbo 2.0L's at the salvage yard...I plan to port and polish them to a stage 3 and take them to a machine shop to give them 3 angle valve jobs with new retainers, upgraded springs and new valves...I just want to know if there are plugs to open and make them turbo heads minus the cams
