Headers are eye candy at the speeds street driven engines run most of the time. All they're really good for is increasing under hood temperatures, leaking, and burning up spark plug wires. Use a 1955-57 265 V8 exhaust manifold on the driver's side for steering shaft clearance, or the rear-exit manifolds for a mid-1980's 305 engine to make both sides look similar.
