Sounds like it could be valves or a serious vacuum leak.
Already did a compression test, guess you didnt see the post. But basically one side of the engine was stuck in the "red zone" according to my gauge and never left about 95-100 psi, whereas the other side of the engine had upwards of 140ish.

One more IMPORTANT thing to note, i just noticed this, but when i start the car up cold i can hear this ticking noise almost like an exhaust leak, once the engine warms up it goes away so i'm assuming this could be the head gasket.
