Comparing these two cams @ .050 duration is really a crap shoot & does'nt tell you anything , seat to seat timing #s will give a better idea on how these camshafts will behave (.004-.050") , could be chalk & cheese.

Depending on intensity #s the smaller stick may be longer @ overlap & be a dog down low.
