Trick Flow matched RB components - anyone used em?

Help gentlemen (ladies too), I am putting together my first big block for a 69 Dart street car with a 727/8 3/4 (gear is TBD). RMS suspension is already installed In the interest of letting someone else do the trials and changes I am hoping to use the matched components in the following:

Trick Flow® PowerPort® Top-End Engine Kits for Big Block Mopar 440 TFS-K616-620-576

The motor will use a 512 stroker kit from 440 source in a '72 motorhome block. CR is planned to be 10.5 or close to it.

The #s they forecast from a smaller displacement block is here:

As I said I am looking for advice. I was born a poor white child who really needs to make the most of component choices. My brother is a die-hard Mopar guy but he has half a dozen small blocks laying around so I am stealing an RB out of his shed.

Please give me some thoughts to chew on.
