I would guess about 20 to 30 rwhp gain.

What heads are you think of adding? Unported LS6 heads or a good stage two head?

With your current mods and following the recommended jets for the nitrous you should be fine. With that being said, I would never feel comfortable running nitrous without a wideband. FYI, I probably leaned my N/A setup a point and a half AND I run about a .010" smaller fuel jet than recommended for my setup.

Question: why LS6 heads? I don't think they're worth the hassle, you'd be better off swapping an 02+up LS6 cam. Less money for about the same amount of power UNLESS you plan on putting in an even bigger cam with the LS6 heads.

Oh and as far as your original question, TUNED PROPERLY, the mods you mentioned (headers and LS6 heads) should add about 20-30 rwhp as mentioned by LS1290.
