I suggest you reduce your pilot or your main jet, but not both at once. Contrary to popular belief, a bigger pilot continues to add its contribution to the mixture, even at WOT. A 54 Pilot might be enough, but a 138 Main in a 30mm carb sounds scary-small to me. YMMV.

So, I have a 130 main in my 26mm carb on my purple elite. (50mm BBK, V8 pipe, ct mani). With my wife and i on it i hit 397 degrees going up a hill, do you think upping my pilot jet would be enough to keep it cool?

No, upping the main would but at WOT the pilot does not supply enough fuel to make any difference.
