second to last post has a dyno chart.......its pretty good information.
as for your headers turning gold, there is nothing that i have heard of to prevent this other then having them ceramic coated.........

 

Jet Hot coating may help retain the finish. It'll also nearly double the total price of the header as well. But another added bonus is that their coating is shown to significantly reduce under hood temps and is supposed to be very durable.
