Oil Filter Adapter

Working on a 1965 Dart with 360 and TTI headers. The oil filter adapter is leaking severely upon cold start up. The existing adapter is aluminum. Is there any benefit to replacing the aluminum with an iron adapter? I have to pull it off to change gaskets and mounting bolt anyway.
The benefits I can think of are: Making it look more stock, improving the filter angle, and less prone to warping. There may be more..... The cast iron one adds a bit of weight though.
