A GM head gasket. Can you maybe provide a little more information? This is not a common problem with a SS.
If you have any miles on it you will want to replace the timing chain an guides while your at it.

My 2009 SS has 84,000 miles on it. It's building up pressure in The coolant system, when its running. And runs a little hotter than normal. A friend of mine ran a pressure test on the coolant system and there were no signsof leakage.
I was told that, that was the signs of a blown head gasket.
Any ideas or advice?

A compression test and a coolant system pressure test will determine a bad head gasket.
I'm of the school, pull the head, have the machine shop do the valves and head surface
A new timing chain and gears set, a water pump and head gasket, and enjoy the SS for another decade or so

Before pulling the head, you should test the coolant for contamination. There are test kits available at parts stores. This would tell you if a blown head gasket was forcing combustion air into the coolant system.
Now, you didn't state a loss of coolant, but if that's happening, then pull the spark plugs and check them for signs of coolant burning in a cylinder.
I would try these 2 things first to verify it is actually a head gasket problem.
On a side note. If the car has ever run over 260 degrees, then you probably do have a head gasket(or worse) problem.
Temps that extreme will usually spell the "kiss of death" for the LNF engine.
