Hijack attack!
I'm trying to discern the best place for my coolant connections. I have a variety of heads that seemed to have fittings and sensors in different places, and several thermostat housings with or without ports.
The heads have a port on the drivers side rear, and on the passenger side front. I see a diagram that shows hot water supplied from the front of the head through the bulkhead, then back out to the water pump inlet. I also see the water temp sensor at the rear of the head.
But on YouTube, I've seen temp sensors in the thermostat housing, and I've also seen the temp sensor in the front of the head and the heater core/carb base water source moved to the thermostat housing. It seems like there might be different cooling acumen based on environment, I'm in NorCal, around sea level (`351').
I know it's hard to go wrong with factory routing, but maybe I can go less wrong if Ford's cooling/monitoring philosophy changed through the 60's/70's/80's.

I know Ford's used to use a ported vaccum switch in the thermostat housing.
You can run a temp sender in the thermostat housing. Some people say it doesn't work. But, if you have a thermostat with a 1/8 hole drilled in it or some stats have jiggle valve built in. It will work. My FiTech coolant temp and my dash temp guage are usually 1-2 degrees off. Dash gauge is using the stock location. FiTech is using the thermostat housing.

I guess I am old school and like the Dash's Temp Gauge Sender to be at the back of the head as Ford put them on the older engines.
Sounds good, thanks.
