All cylinders filling with water
The reason I am waiting on torquing them.....I am be patient and letting everything settle in so to speak.
Sorry, but that makes absolutely no sense at all. Torque the studs to spec. Nothing is going to 'settle', move or do anything if you wait. Finish the job.
Pressure test the cooling system before you fire it, make sure you can feel water in the rad hoses. Bleed it at start up, make sure all the air is out of it.
Did you look closely at the intake and the rest of the coolant passages? Only way I can surmise you could have had coolant in both banks was if it was being pushed and pulled through the intake or by some other common passage between the heads. You should be looking for a cracked intake, blocked passage, mismatched gasket, bad water pump etc, something broke through or got stuck in a passage, etc.
Hard to believe that head bolts could cause your problem. Were they loose when you took it apart? Did you blow compressed air down the bolt holes? Pretty sure you would have observed significant compression loss and the engine would have barely ran at all if the head bolts were not providing enough clamping force, let alone overheating.
