Dawg, I think the main purpose of this exercise is to see how applying 21st century technology to these heads can benefit, compared to the old standard 1950's California Bill porting techniques. Since the 1950's is the last time anyone seriously looked at these heads and engines from the performance standpoint, it is interesting to see how much more the 21st century spin can take it to a much higher level. Flowbenches didn't even come on the scene until the early 70's, so the techniques they used back in the 50's didn't really have any data for trying to maximize camshaft lifts or durations with, whereas today you can.
