Question about headers/heads

I have a 391 FT engine, i was wondering if 390 FE headers will fit on a 391 FT head.

My exhaust ports are squares and i think 390 is circles can anyone confirm or deny this?

Also if they would not fit then do they make headers for a 391 FT?

Thanks

FE engine's exhaust ports are rectangular.

You should be able to use standard FE headers, but you "might" have to elongate the mounting bolt holes in the headers to get the ports and flange to match.

Notice the FT exhaust manifolds have an extra exhaust port.
