Try this: First retorque your heads and manifold. Then After you have your engine running where you see some smoke, Turn off the engine and remove the spark plug wires from the pass side and spin the engine a few times then pull the plugs and see if there is any coolant in the bore. Use a long Q- Tip (like you would use to doctor your dogs ears). Check # 3 and #4 first. My guess is that your intake isn't sealing properly
