I would advise NOT using Ilford MGIV for lith straight up, it just turns black within a couple of seconds, BUT, I believe if you make a "normal" print on it, bleach it out, and THEN redevelop it in lith developer you should get a result.

Also, look into age fogged papers for lith printing, most of my RC lith prints are made on otherwise useless (due to age fog) Kodak Polymax III paper.

Good luck
