There's not much to futz with tune wise when doing headers. Any professional remote tuner would have no issue cleaning up your stock tune with headers in <5 logs if they are only messing with MAF and codes. If they do it right the should touch MAP (airmass) tables and that could take a lot more logging, but the right thing to do.
