Me either. Makes no sense, it's like semi-polishing a turd. Good pics Jim, they show the choked Renix intake intake ports clearly. What is gained by using an HO head on a Renix if it can't flow as designed? If you are going to do an HO swap, do it right by swapping in the HO harness, intake, TB, HO sensors, and ECU from a donor. A semi-HO swap is a real half-azzed idea IMO.
