Head gasket replacement is not a job for the average do-it-yourselfer. While a head gasket expiring due to old age is rare, it usually means everything else is worn out to the point of replacement as well. Cracking the head off the engine and peering inside may reveal that everything else got fully cooked, too.

If you have an alloy engine head and the engine got real hot then you may have a cracked engine head or a warped engine head. A compression test would need to be carried out by a mechanic to test and confirm if this damage has occurred.
I am not a mechanic but I have experienced having cars with cracked head, blown head gaskets and recently a cracked block in engine or worn rings (had to replaced last car as engine block damage is expensive to fix)!
Technical theory on engines follows !
If coolant is leaking into one or more cylinders of the engine via a blown head gasket or cracked head or warped head then the spark won't fire and the fuel won't ignite in the cylinder until it cranks over to a different cylinder that has no water in it. On the next engine timed cycle the water would have been forced out of the water filled cylinder and into the exhaust pipe and will come out as steam.
Get a compression test done to eliminate a warped head or cracked head . Hopefully you have not cracked the block as this costs 6000 dollars AUD to fix or $3500 AUD for a Reco Engine.
If it is an alloy head the two metals cool at different rates and warping or cracking can occur. $$$$$$$ costly $$$$$$ to fix
First make sure it is heads and not just an intake gasket. Chevrolet engines are notorious for blowing intake gaskets and being mistaken for heads. If it is heads it will cost around $1000 or more depending on if they are cracked.If the heads are cracked it will be just as cheap to install a new or used engine.
to "fix" a head gasket requires taking off the cylinder head and associated compnents, getting the cylinder head serviced to ensure flat surface and no cracks, reaplcing the head gasket, and reassembly ensuring the proper torque of all bolts, especially head bolts........what makes you belive the head gasket requires fixing
Blown head gaskets for sure, no way of knowing if heads are cracked without taking it apart, there no quick fix for this, only fix is to take it apart and repair as needed.
V6? these are famous for head gaskets and cracked heads. the heads will need to come off and checked over for cracks and repair or replacement by a automotive machine shop.
you have either cracked the block cracked the heads or taken out the headgaskets. this can be an expensive fix to do it right you will need to rebuild or replace the engine.
This sounds like a typical head gasket problem. Check the block and make sure it is not warped or cracked if it is not replace the head gasket and your problem should be fixed. Avoid using it this way as you will do more damage and crack the head until it is fixed.
