what cam based on this heads flow characteristics? OK cam / head gurus, would it be unproductive to use a cam that had more than .550 intake lift with heads that lost intake flow beyond .550 lift? (see attachment) Does the downturn on the graph indicate loss of laminar flow (turbulance)? Does power production just level off at this point or would I start slowing down if I, let's say, ran a cam that had an intake lobe of .598" lift? Should I be lookin' at the .550" lobes? Thanks in advance for your thoughts!

Put an intake in front of that port and your peak .550 number will undoubtedly be less (how much depending on the quality of the intake) and you will probably just see your .600 number flat (or very close) to your "actual" number thru the intake (not dramatically falling off like your flowbench results with a radius might indicate). Point is the higher lift cam will allow the engine to see the same "net" peak airflow for a longer period of time (measured in crank degrees) and make more power because of it. I would opt for an XER lobe with total lift in the high .500's approaching .600
