I’d like to see the flow sheet on that. By my math your head would have to flow 494 CFM at 28 inches.

Its 100% possible my numbers are wrong, I am no professional at using a flow bench. I can say they were consistently higher than my unported W2 Econo heads that flowed 268. What suprised me was .600 Lift was only 3.42 cfm better than .400 lift.
