take pity on a fool, what am I looking at here? is the top line throttle opening, cam lift? are the other numbers ft3/min. I see it compares the different heads but I'm missing the boat on the rest. Do you have numbers for the e6's?

[DuceAnAHalf]

the numbers at the top are the lift at the valve, so if you have a cam with lift of 484 , and you have E7's, you would flow about 152 ft3 a min on the intake and about 116 on the exhaust. the table is hard to read because the forum would not let me post it in the way where it is more readable

No E6 head flows??? Just curious.
