header question

been looking for header for a slant, and from what i can tell no one makes shorty headers for the slants.

my question is, how close are the jeep 4.0 headers to a slant? i know the mounting flange is WAY different, but does anyone know how close the ports are between the two?

thinking maybe buy a set of slant flanges off ebay, buy a 4.0 header and cut the flange off, then modify the inlet tubes to fit the slants ports
