Anyone have any numbers of HP/MPH gain with the installation of OT headers? Is it a huge gain or a moderate gain.

It can be as much as 5+mph depending on the exhaust you have, in most cases it is about 3mph but some none.

They are not OT headers, they are TT Lightning headers, but I picked up 250 rpm from the stock manifolds.

Its hard to say. Each time I went I did a couple of wot runs by myself. The problem is, the conditions were always a little different.
Sometimes it was windier, or the flow down river was faster, or it was hotter, etc.
I'm guessing it was about 2-3 mph faster with the headers though.
