Update
I took the end cap off the heat exchanger and took a picture of the inside. Looks all clear (see pic below).
I also took the hose off the heat exchanger that was coming from the exhaust manifold and filmed it while turning the engine over. Looks like there is good flow and the coolant is clean:
When I warmed up the engine, the hottest part to touch was the head on the opposite side of the thermostat housing (where I’m pointing in pic below).
My next step will be to remove the thermostat housing and see if there is a thermostat that is stuck but I need to get some gasket material first so I can put it back together.
The other thing I’d like to do is get a heat temperature gun and compare the temperature of the engine to the gauge reading in the cockpit.
