How much more Power with headers?
My car is stock SS 6 spd except with ported Throttle Body. How much more HP and Tq can I expect with Long Tube headers going through my stock NPP exhaust? Its a 17' that I bought new, now with about 68k miles.

Headers in general have a range of about 20-30 rwhp give or take depending on tuner. I think some people have hit as high as 35 rwhp.
Not sure just how much torque though. Unsure on ported TB either.

I would add a CAI intake if you are going to put headers on. A cam change and CAI would work real well with headers also.

Catless LTH on a pretty much stock car, +25-30 whp. Catted, +20-25whp. Cat delete pipes with factory headers, 10-15whp.

I had a Rotofab and a Soler 87 TB when I added my Kooks headers and green cats. All else being stock. My gain was around 28hp

When you pull the trigger make sure you heat wrap them, starter overheating is a common issue.

I guess you could look at it this way, the 455 HP SS is rated at 4.3 sec with M6, (4.0 sec with A10) 0-60 Mph, the 650 HP ZL-1 is rated at 3.7 sec with M6 (3.5 sec with A10) 0-60... I would guess 30 extra WHP might knock 0.1 sec off your 0-60 at best...
