Is there a way to distinguish a crack in an engine block versus a defective head gasket through palpable differences in vehicle performance?

THERE IS NO REAL WAY TO TELL FROM DRIVEABILITY ALONE. BOTH PROBLEMS WILL CREATE LOSS OF COOLANT AND CREATE STEAM FROM THE EXHAUST AND IN NEWER ENGINES CAUSE COMPUTER CODES TO COME UP AND VERY POOR DRIVEABILITY. BEST COURSE OF ACTION OS TKE THE CAR TO THE CARWASH AND CLEAN YOUR EGINE COMPLETELY. (IF POSSIBLE TO DRIVE THIS FAR) NOW 2 OPTIONS IF YOU HABE A COLLING SYSTEM PRESSURE TESTER KIT USE THIS, IF NOT YOU WILL HAVE TO START THE ENGINE TO DETERMINE WHERE THE LEAK COMES FROM. BLOCK CRACKS ARE NOT GENERALLY SMALL AND POUR OUT ALOT OF WATER FAST BUT HEAD GASKET LEAKS GENERALLY APEAR WHEN ENGINE IS WARMER AND COOLANT IS UNDER MORE PRESSURE. GOOD LUCK WITH YOUR QUEST
