When we did Taylor'* headers I remember looking at the front manifold...ACK! Needs major porting.
Don't remember the rears, but again the guy I know didn't bother with the rear (but he'* lazy like me).

Look in the rear one if you take it off. You'll see the individual pipes extend about 1" past the welds into the rear manifold. I'd say the interrupt the flow from the crossover.

If you have a air compressor, buy a cheap die grinder and a carbide bur. It will hog all that metal out and there are alot of attachments to make the surface mirror smooth. Like a diamond polisher. These are not big investments. A Demel tool would work if you have the time. They make carbide burs for those as well.This is not a expensive thing to do .No I haven't done this yet. I work on plastic molds that make BMW parts.
