While your exhaust and intake manifolds are out why not pull the freeze out plugs and the 2 drain plugs
You would then really be able to clean out the water jacket around the cylinders — most likely the freeze out plugs could use a replacing anyway — use good brass plugs instead of steel
I would bet that there’s a ton of crap in there especially if you used some sort of stop leak
