full throttle hesitation Q?

Need some help guys. I have a 400hp small block with 750dp mech. sec. with proform body and any time I open the secondaries or full throttle under a load it hesitates bad and then pulls hard. My 60ft are 2.0's and et's are 12.80's at 107. I know there is more to be had at least mid to low 12's. Carb jetting is set at proforms stock settings 72's in front and 84's in rear, 30cc pumps front and rear, 31 squirters f and r, played around with jetting and the squirters but had no change in hesitation, all 8 plugs are the same medium to dark brown and a little oil on the bottom 2 or 3 threads. Any info you guys can give me would be appreciated.
