HELP!! NC23

Hi! I’m Gustavo from Argentina.
I’m restoring/rebuilding one a CBR400RR NC23 J. She came with two exhaust camshafts (nope, no intake camshaft :o :o :o ). For what I’ve seen they seem to be equal, except for timing marks, are they? I can’t find any intake camshaft around (I’m from Argentina, and we have very few of these bikes around). Do you have a valve timing diagram (the one with the degrees)? Or any other way to get timing in both camshafts ok (without the intake mark)?
Thank you very much!!
