I said to drain water and oil then change oil run without water and dump oil again, without water so you could flush engine, no reason to flush with water still in it as the oil will just get more water... get the motor flushed now, do not wait... it will be fine.
Proper lube on headbolts can make a huge difference in what actual torque is! ARP head bolts don't stretch like stock ones do.
I've never seen that before? And they have to be done in sequence usually from inside out, look at your manual.
