Header options for a B-engine stroker in a Dart?

So if this car is mainly going to be street driven and only operated at peak rpm for maybe 5 to 10% of the time?and spend the other 90% under 3500 rpm I think the Schumachers will be fine, granted you'll be giving up maybe 10 or 15 hp on the top end but you already have a set of headers on the car that you know they fit. I would run what you have.
