Digitizing Cylinder Heads Help

Our people say they can get to 99% accuracy from a port, however, when going to the seat area, there are metrics like "picking the throat size." In this case we chose to go 92% that reduced flow quite significantly, so be very careful. We are doing a 642 cubic inch Pontiac engine and the throat size is the limiting factor. We brought the flow back with a carefully constructed intake manifold runner by Mr RPM himself, "the Kat" Rick Katterjohn.
