Thanks guys for the replies. Glad to see folks out there can make heads & tails outta this flow chart!

Given the issue of missing information, I think for true accuracy's sake I'll have these heads flowed again.

I would also assume that those numbers are the percentages of 400 cfm and 300 cfm at 28 inches respectively. I have used at least 3 superflow benches to flow the same head casting number and it is typical numbers for those heads.

Those numbers are the percentage of flow read from the inclined manometer, they are multiplied by a factor at a given flow range.
