My venture is starting rough or taking 30 seconds or more to turn over. I pulled battery and it is fine. What can it be next?

Hey everyone, im hoping i could get a little insight on a car im working on. I purchased the car and the seller told me it had started overheating and acting like the head gasket was starting to go bad but not blown, there was never any oil-coolant contamination, and he gave me the full gasket set for the engine with the car. I drove the car home, had to stop twice to add coolant because it was all pouring out the coolant overflow, and then tore the engine down. The head gaskets did not look that bad, the lower intake gaskets looked ok, and the upper intake gaskets looked like crap. I replaced all of them since i had them, also replaced the following, spark plugs (gapped .060), plug wires, thermostat, coolant resevoir lid, power steering pump, valve cover gaskets, pcv valve, throttle body gaskets, exhaust manifold gaskets and bolts, fuel injector o-rings, air filter, and oil/ oil filter. After i did all this i put the engine back together and started it up, it started right up but is not idling smooth and also is still spitting all the coolant back out the overflow. Ive flushed the system and burped it 3 times for 45 minutes each time and it still does it. I also ran a compression test and got 130psi from 5 cylinders and 120psi on the #5 cylinder those numbers sound low but im not sure what they are supposed to read. Also the small vacuum tube connected to the pcv valve is collapsing when the engine is idling and the engine seems like its stalling out. Ive had suggestions that the heads where warped and now i need to redo the head gaskets, the heater core is bad, something is wrong in the vacuum system, and the water pump is bad. So with all this info can anyone tell me what it sounds like im hoping i dont need to redo the head gaskets but that looks like where its heading. Thank you to anyone that helps.To POST a message, please
