The steering box is conflicting with the manifolds I have and headers I have on hand. Anyone have a list of manifolds and or headers that fit?

They're available on Ebay frequently for very low prices. It has a front outlet and is made to clear the steering gear. Using ANY kind of header except equal-length tubes from each exhaust port is foolish and does nothing for performance at engine speeds where street-driven engines run. 30-something years of dyno runs we did while building round track engines proved that to me repeatedly.
