Sorry about the eye chart appearance of all the numbers up there.
Here are what the columns are:
The upper table of numbers is intake flow, and ratio of exhaust to intake flow.
The lower table of numbers is exhaust flow.
First column is valve lift.
Second column is for a stock Magnum head with 2.25" intake, 1.88" exhaust.
Third column is for the Magnum head fitted with 2.35 intake, 2.00 exhaust valves, but without any porting or seat blending.
Fourth column is for the ported head with big valves.
Fifth column is ratio of E/I for stock head.
Sixth column is E/I for the head with big valves unported.
Seventh column is E/I for the ported big valve head.
