Not necessarily.
Blue smoke suggests burnt oil, so it COULD be that the HG has failed between and cylinder and an oilway, but it could also be a valve stem or piston rings
Have you got a compresion tester? That ought to rule out the rings.
Id also check your oil/ coolant for mayo (classic HG fail sypmtom) and whether the oil level has dropped
