it seems all your measurements are in thousandths of an inch
cam lift:
the amount the cam lobe is pushing the push rods.
321 and 289 divided by 1000 will give you the amount in inches...
ie 0.321" and 0.289" (times this by 25.4 if you want them in mm)
duration adv:
most likely means the duration of the cams lobe (how long each valve stays open for)
measured in degrees relative to the crank shaft.
ie 264 is the valve stays open for 264degrees of the cranks rotation.
duration at 050:
means how long (in degrees relative to crank) the cam holds the valve open above .050 of an inch (or maybe how long the cam holds the push rod above .050 of an inch).
valve clearance:
distance between the valve and the lash pad when the valve is shut and the cam isn't pushing on the push rods.
valve lift.
the distance the valve comes away from the cylinder head (ie how far it opens)
