What would it take to make 1.44 lbs-ft per cid ?

You are correct again, TONS of time was spent on those heads. Every single port was flowed and worked and reflowed until I was happy with them. In the end they all flowed within 3 cfm at all lift ranges and they flowed 275-277cfm on a 4.06" bore. So much work and effort went into those. J.Rob

Is there a velocity number you shoot for ?

From what I understand 260-285 fps based off average cross section is the supposedly the sweet spot but seems to be asking for fairly large ports, if I'm doing the calculations right seems based off 371 with the 277 cfm heads would need a average csa of 2.56" & 207 cc for 260 fps.
