New Thor heads flow 530 and 370 cfm unported with 2.5" and 1.88" valves at .750" lift.
Cool Intake allows good access for fine tuning too.

Yeah I read a CNC outfit in Michigan is getting 580, not sure what kind of lift but I suspect much higher than .750"
Not sure of the Port size/volume.
Would Love to run these but headers would be hard to get fabbed. I have the "peanut" A-heads which have been around for 20 years and those were hard to get headers for due to their size. They flow 455/335 at .800" (CNC'd) which will do for now

Of course you are absolutely right.
I care more about .450", .550" and .650" lift and air speed. These heads are made for all out big inch racing, although I bet they would work on big inch, high rpm or big blower motors in front of #6 drives![Cool Smiley 011](/forums/images/smilies/cool-smiley-011.gif)
I was trying to be funny and I am an overly proud Ford guy
