How Hot Is Too Hot ????

Too hot is when the coolant reaches its boiling point.
Engine will run all day long at 250* as long as the coolant isn't boiling.

Rusty,

As Ken said , check everything over really close... Try another H2O gauge to be sure yours isn't stuck & see if they read the same ?? Also, make sure there's not restricted area or plate anywhere in the engine, hose, radiator etc.
I would then try letting the engine run @ 2-2500 RPM & see how long it takes to get to 220-230 * degrees temp ??? Sounds like you have something restricting the flow, try draining everything and see what comes out. When did you start having this problem, after the fire or before ????

let me know.... Are you coming to VMP this weekend ??

What kind of car is it Rusty? Some of these later models are hard to get all the air out of the cooling system. I added bleeders on the back of my heads to get the air out, while the electric water pump is running. Engine off. If mine gets to 160 in the shut down area, it's back to 135/140 by the time I get back to the pits. 230 is pretty hot in a short time.

I had similar issue, was wondering if can hurt the rings, causing bad leak down numbers.

Had that happen a few times. Didn't hurt anything, except my nerves.
