Agreed, flow bench matching in production would be cost prohibitive. Based on some experience I have had in the far past with v8 manifold porting there are probably some areas in every upper and lower manifold that need to be touched and some areas that should be left alone. Find those areas and verify with flow testing on one prototype pair of manifolds, then duplicate the pattern on production manifolds. The matching won't be perfect but chances are it will be better than stock.
