They are different. Manifolds use a donut gasket, and headers use a flat gasket. Some headers have a ball and socket that uses no gasket. Either way, this connection will be in a different location on headers vs. manifolds, so exhaust pipe modification will be required. Your exhaust pipes will need to be extended to reach the manifolds.
