Almost any engine will run with a blown head gasket. Having said that: NO engine was ever meant to run with a blown head gasket!!!! Several things could be happening simultaneously while the engine is running: coolant could be entering the oil pan, causing a loss of friction protection, destroying the bearing surfaces of the major rotating members; oil could be entering the cooling system, seriously diluting the coolant, reducing it's ability to remove heat from the engine; third, oil and/or coolant could be entering the combustion chambers, fouling the spark plugs (inhibiting ignition spark), and forming unwanted unburned deposits on the pistons, cylinder walls, and compression rings, causing accelerated wear to all moving parts. DO NOT OPERATE AN ENGINE believed to have a blown head gasket---it will destroy the engine.
