Trick Flow small block heads

I have no complaints with Edelbrock heads. Curtis Boggs did mine and they went 6.57 @ 104 with a 1.38 60' in a 3260# street/strip Dart. The engine was 408", 10.8-1 with a 236/242 @ .050 flat solid, 727, 4.10 gears running pump 93.

My current 434 with ported Indy heads and intake, 700" lift solid roller has only gone 6.40 @ 109 with a 1.40 60' @ 3350# on pump 93. I'm hoping the new converter will get my 60' down where it needs to be and put me down in the low 6.30's. That .2 has cost me a hell of a lot of money.
