Which size header makes the most h.p.? Can anyone tell me how much lt's produce, mid lenght produce, and how much shorties produce?

You have them in order already =)

If you dont have emmsions, its a no brainer...get LT's..

If you do, then if money isnt an option, get the mid-lengths: RK or AS&M, Very sweet headers..

Then if not, MAC shorties are good.

HP wise, it would all depends on what other mods u have. But LT's are awesome if you plan to do a bunch of stuff down the road.
Good luck
