Ron, I already have an intake and exhaust port model in 3D for an 848 head, and am working on getting some flow #'s for it as we speak. I will be blending 21st century technology with these older heads to see what benefits await to be discovered. I also am going to use some Lump port techniques on them as well. I also have a 302 GMC head to do the same thing to as well. Im sure that you bowl cut under the valves on your head, what size did you end up making the bowls for the intake and exhaust.
