a budget is all relative, your gonna spend a few thousand on a motor build, one of the most important components is the header, dont skimp on that.
i know you just picked one up, im not saying in any way they are bad headers. they are good headers that make good power. with every part of a motor there is always room for improvement.
what im trying to say is that its all relative to what kind of motor its on.
your header on your proprosed build, will perform just great, but in the same sense im sure you know theres still alot of power to be gained from a better design. hp is dictated by the wallet at the end of the day !
