Trick Flow 440 heads, The Real Deal?

As seen, the larger the cylinder bore the better the head can breath into the cylinder.
My W5's peaked @ .600.

Bore .......cfm @ .600
4.185 ........ 312
4.030 ........ 294

If your going to build a 440 stroker small block, here are two ways it can be done.

MoPar has a 440 @ 4.185 X 4.00 stroke
Rod Bloomer's kit @ 4.030 X 4.25 stroke

Price aside, I don't know the difference any way, which would you build? LMAO!
