Ether where the extreme is a suspect and ether difficulty in cooling is a suspect or problem and/or your going to add extra coolent removal for superior head cooling comes into play.
The best spot to take water out of the head is the center where the two exhaust ports are together.
Post 21, picture #2 has a max effort coolent removal modification on the W9 heads in the picture.
Also seen in that shot is a modified thermostat housing. There, the coolent hoses attach under the thermostat for a quick exit out of the engine into the radiator. It looks like a mass exodus map.
On engines with lesser heads than the W7-8-9 series, the below thermostat adapter can be used. This one from Joes racing products has 3 ports that are the same and one slightly smaller where my MP mechanical temp gauge is hooked up.
On this, you can run 2 coolent lines to it and plug one up or combine 2 lines into one and use all 3 available.
Plumbing water into the bottom middle of the block introduces cool water into the center of the hottest spot in the block and up to the hottest part of the head, the center.
