You will never tax the tranny with the Roush kit, unless you cook the tranny fluid.
With the 47 lbs. injectors and the Twin 65mm TB, you'll only get 500 RWHP and 520 RWHP max with 93 octane on a cold day.
Honestly, I wouldn't do headers, I'm around 725-750 at the crank depending what drivetrain % loss you want to use.
In any case, I get 561 RWHP with full stock exhaust, stock tranny, for the past 8 years.
Whipple's Ford Tuner says I would be around 580 RWHP with headers.
The one bigger benefit is the Torque would increase another 60 ft-lbs. to the wheels.
But still, for the money the little increase in power, the extra noise,
and daily drivability is compromised slightly due to the position of the front O2s in the collector of the headers.
Just doesn't make me want to do headers.
Now, if I had money burning a hole in my pocket then yes, I would do it.
