Trick Flow 440 heads, The Real Deal?

Confusion reigns all across the internet on the flows from these cylinder heads. There are so many different ways to set a cylinder head up on the flowbench that I've taken the time to flow the head many different ways. I tested one port 5 different ways. (1) no radius plate, (2) 1/4" clay roll, (3) 1/2" clay roll, (4) radius plate #1, (5) radius plate #2. Radius plates can come in different thicknesses, radii, and angles of approach. (4) & (5) are just two of the more that twenty radius plates we have.

Lift............(1)......(2)......(3)......(4)......(5)

.100..........74.......75.................75.......75
.200.........151.....153...............153......151
.300.........206.....225...............225......219
.400.........229.....274...............279......272
.500.........236.....291...............317......320
.600.........239.....295...............323......338
.700.........239.....284.....312.....315......333

On my bench, every intake port I tested would stall between .600" and .700" lift.

I have revised the way I open the exhaust valve and here are the new results.

Lift..........no pipe........2" X 4" long pipe bell mouthed on the end and angled slightly up.

.100...........52...............53
.200..........119.............133
.300..........161.............185
.400..........192.............227
.500..........211.............251
.600..........223.............267
.700..........230.............273

I hope this clears up some confusion. I've messed with this enough for now and I still have to flow a service prepped Victor head before I can go home tonight.
