Highest CFM flow heads, small black, Completely, under $3000

There was a build (a single one IIRC) of a stroker something here on FABO a few years back that didn't quite perform up to the expectations. It was blamed on the heads though a few important questions (by RAMM) were left unanswered. I am wondering whether they are 'fixed' now or whether they just had a bad start back then with one unfavourable 'result' posted here...
