It depends on the gasket you are talking about and in some situations the position of the blow (leak) in the gasket. A head gasket on a car for example seals the space between the cylinders. or the space between the cylinders and the oil ports or the space between the cooling system and the cylinders. Should any of these Blow you can end up with water or oil inside the cylinder head which can ruin your motor. or if gasses are able to move from one cylinder to the other it will lead in irregular operation and a loss of power. In any case if it is blown it will need replacing. heads must always be tightened down with a torque wrench to stop it from cracking or becoming distorted.

if it is just a blown exhaust manifold gasket it can ruin your valves, so replace it correctly and make sure everything is clean before putting on the new gasket
Loss of power and hard to start.
Because the head gasket is blown.
No it will not. The only thing that will fix a blown head gasket is to replace the gasket.
what are you asking here? PLease be more specific ...like - how do I know if my head gasket is blown, or what do I do about a blown head gasket ......
Sure it will start with a blown head gasket. But, if you continue to run this engine with a blown head gasket you will destroy the engine.
There are several possible indications of a blown head gasket: If the head gasket is blown between adjacent cylinders there will be poor or no compression in either cylinder. Poor compression in any cylinder can be caused by a blown head gasket. That condition can also be caused by a burned valve or piston. Coolant in the crank case can be caused by a blown head gasket. Compression in the coolant can be caused by a blown head gasket. An engine with a blown head gasket usually loses performance and runs poorly or not at all.
Yes, I blown head gasket will definitely effect the emissions.
With a blown head gasket the engine will still run, poorly with issues, but run. A blown engine will not continue to run from that moment on.
No, a normal tune up cannot cause a blown head gasket. A blown head gasket normally is caused by an engine overheating or by a defect in the gasket or head. If it happened right after a tune-up that is just a coincidence.
No, the only permanent fix for a blown head gasket is to replace it.
