For cooling/water any point above the rocker cover bottom lip is above the water in the head, I have a Westfield breather T in the 16mm hose from water pump to inlet manifold and make sure it is at the highest point.
The breather/catch tank should have the hoses entering higher than the top of the rocker cover or oil mist will travel by gravity to the tank and fill it very quickly.
Look at Burtonperfomance web site to see diagrams
