I just spoke with my machine shop yesterday about this subject and I think I am going to add the fitting to the head. Cleaning the engine is not an issue since the engine is completely apart. Still would like to see how the hose is connected into the heater return to the water pump. I appreciate the suggestion to go with brass or copper for the fitting. My 1994 GMC Suburban has a fitting off the back of the engine similar to the Lotus engine and it was original from the factory done in steel. Thing rusted out twice before I finally told them to install a brass fitting. Seems to have solved that issue.
