Pretty much how I saw it fellas.... 572" of Hemi IS a big engine and big engines swallow up duration and you can add 8-10 deg of duration @ .050" with a roller compared to a comparable solid.
Regardless of the theory I feel the engine made very good HP/TQ at livable/non parts hurting rpm, which was the whole plan from the outset so id say we'd achieved what we set out to achieve.

Thats because you are not taking into consideration the displacement of the OPs engine.
What cubic inch were the Hemis you built, and what cams did you put in them? How do they run, or how well did they dyno?
As someone else posted, I wouldnt consider a 270 cam in a 572 a "big" cam.Your conventional thinking of a .650 is simply too small for this application. I'd say Bullet hit it pretty well. Also notice the 112 LSA.
