I have a 2005 Buick LeSabre, it ran hot one morning and i heard this clicking noise coming from the engine like the valves were'nt getting oil or something. Now when a crank it the engine runs like it has a bad plug or two and there is constant bubbling into the water reservoir while it's running. I have been told that it's a blown head gasket and am asking around too see if that's what it is or could it be something else, the constant bubbling in the water reservoir is what has got me? but anyone that could give me some suggestions on what it is would be much appreciated.

Sure sounds like a blown head gasket.

Most definitely a blown head gasket between the cylinder and the water passage as indicated by the gurgling sounds your hearing. It is actually the engine compression being forced into the cooling system where it gets bleed off or else it would blow out the hoses and or radiators ( this means the heater core as well as the radiator.) You should also check for a warped or cracked head and also check the engine block.. The fouling of the spark plugs in the affected cylinders (probably 2&3 or 3&4) is the engine coolant and water being sucked into the cylinder on the intake stroke which wets the plug and causes it to misfire. this answer provided by Millerwright1@Yahoo.com

It may be the upper intake manifold gasket, most likely, due to engine design. Google "2000 Buick Lesabre Intake Manifold Gasket." A set of manifold cover and gasket is available. Videos on the issue and how-to are offered on YouTube.
