The cam card clearly denotes what it SHOULD be - and that the checking clearance is 0. What he is probably going to find is that the cam does not match the card - which I've seen MANY times. If the grind itself is off, there is nothing he can do to "fix" it . . . he can advance/retard it, but that is it.
