Well,  when you machine the places which add most of the airflow you will tend to find water.  

To be pretty safe ... Remove most of the pushrod bump in the intake runners, machine the wall away behind the pushrod bump into the bowl as mush as you dare and pull back and lower slightly the short side radius near the exhaust port then round the entire short turn

Don't lower the exhaust short turn other than to round it. Pull back the wall behind the head bolt hole.

Anything else and you will probably need a welder.
