Did it leak coolant into the motor? It may be water logged and unfortunely, water will not burn

Car was running when it was parked, upper intake was replaced, all cylinders blew out several times, 150 lbs psi on all cylinders, have fuel and fire, but unit doesnt want to start. Wants to but will not start. Looked at GM website and it mentioned lower intake gasket deterioration after 60,000 miles. Car was running before repairs were done, could lower intake gsket be the problem?

No. If you have fuel and fire as you say, then it should go.

Did you replace the plugs?
