^^^ that makes 100% sense. water went from exhaust port to EXHAUST crossover.
This week, when I first pulled the rockers off to remove the head, I noticed that two of pivots on the rockers were upside down... the flat part was down on the stud, and the round part was up. I guess I installed them wrong after reinstalling the head. I feel really embarrassed to admit this.
believe HERE was your problem. Now just have to see what damage has been done from said mistake. Posible burt exhaust valves or just depending on how the studs are (tighten to 20 lb torque to seat? or 1/2 turn after zero lash?) designed as to what other components could be affecte. The tighten to seat...could pose alot of damage! valve spring bind, seal damage, pushrod bending.....If they are NOT bottle-necks...then probably just rocker arms, balls, and a little touch up on the valve/seat
