Can't remember - I saved it to My Documents quite a while back - but the name of the file is "Cam-Craft Factory hi-po cam specs."

Camcraft catalogs are one of the sources that list durations at lift (.006/.004 etc) for those cams.
Cam 5214 671 may be a later version of the earlier cams or Camcrafts number?
Part number changes may have been just a subtle change in design.
