Around here, when someone refers to the geometry correction, they are usually talking about B3R, B3 racing. He has a kit that moves the shaft to the proper place for roller rockers. Check the tech pages at his website. Google B3 racing. (its not the european site that also comes up)
So if you do not use roller rockers, you don't need the correction kit? What about the 273CI stock adjustables? I was planning on reusing my stock rocker arms / shafts from the 318. Is this doable with a hydraulic roller cam / lifters?
