will a set of 440 HP factory headers fit onto the 70 Coronet 383

Factory Headers?? Factory HP Manifolds yes they will work. Also a lot of aftermarket B body headers will also fit.

Yes Factory HP exhaust manifolds
Yes, factory HP manifolds fit fine.

Depending on the year of the manifolds, the clocking is different for the head pipe connections.

70 manifolds and 70 car/exhaust should be a bolt on connect the pipes and go.

I should clarify. This is assuming the car had hp manifolds before. If it had a big block with the “log” manifolds or a small block. The pipes will not connect without reworking the head pipes. But the hp manifolds are exactly the same between 383 and 440.

I can state from experience many moons ago 440 HP manifolds from a B body will go on a 383 C body and OEM dual exhaust bolts straight on.

Which OEM exhaust, for the B body, or C body? I believe that the C body exhaust is unique and will only work with its own unique driver side exhaust manifold.

The HP manifolds came off a 70 Charger RT and went on a 65 Sport Fury. The exhaust was Walker for a 65 Fury 383-4.
Follow up question, is the clocking of '70 non HP or 2 bbl exhaust manifolds the same as '70 HP manifolds?
Edit: I ask because I got '70 330 hp 383 (not 335 hp) manifolds which had the dual exhaust. Were 383 2bbl manifolds clocked the same?

drivers side b and c are different for steering box interference
