Break in with TTIs

What do you do when you are dynoing a new motor with w-2s and the only headder you have are a new set of tti w2 coated race header? Right now running eddies on and 416 made 583 hp@ 6500 and 544lb torque @ 5900. The eddies only flow 280@ 575 lift but drop off to 250@ 600 lift. I came accross a set of batten w-2 alum versions that were flowed 340@700 lift
I hope to get 700 plus out this combintion. What do you think?
