EFI manifold versus headers

Ford 300...
I have read that running an EFI manifold is just as good as a set of headers to let the engine breath and cheaper.

What is a good source for an EFI manifold?

Junk yard or eBay. Look for 4.9L F150, F250, Bronco or vans 1987 - 1996.

I’ve had both headers and now I have the EFI manifolds and honestly I couldn’t tell the difference in performance but sound yes the header definitely sounded better that’s the only reason I would go back to the longtube header.
