Andy,
1/4 inch is about spec on some stock cams. What I suggest is to compare that 
lift to the other exh lifts on that engine. If it is less, then yes, either 
the cam or the lifter is very worn. Why not pull the lifter and look at its 
foot. That should tell you, since any wear will probably be on both the lifter and 
the cam lobe.
