Not really fair there redwhitekat... My factory replacement 4.6 never overheated and I owned it the entire time yet it still developed a cracked block after about 140k miles... I did not kill it. Nor did I kill the engine it replaced... Which was the one it came with, replaced under warranty due to the front cover dowel pin issue. Developed a tick shortly after I took it home from the dealer.
A cracked block is not necessarily the fault of the owner.
But yes, get yourself a way to monitor your temps in real time. Ultragauge is great.

I guess you're in a bad mood today, that's ok. It happens.
Now, judging by the actual information and not guessing, it's clear by the oil that doesn't smell burnt, the cylinders that are not damaged and by the HeadGasket that didn't even fail, that this motor was NOT over-heated by me.
Instead, the block finally failed one way or another and when it did it CAUSED the coolant system to see hot combustion gasses and thus read high. I tried to explain earlier to you that a block doesn't overheat in 15 seconds flat, I suspected I was reading combustion temps in the system and not water.
No reason to get bent out of shape and go on a rant, especially when you're incorrect.

Beat me to it, I don't know the original ownership of this vehicle either way. We don't know if it's even cracked, it could have the very common 2004 block that had pinholes in the casting that eventually corrode away, due to Dexcool issues or whatever is causing it. A good way to monitor temps is great no doubt and the moment I drove it home I tried to sync it with both my real time BT gauges to no avail. Not like that would have helped me in this case anyway. The overheat is the result of the failure, not the other way around in this case.

Camel Trophy
^ Brilliant idea and ironic. I just did this a slightly different way but same concept a few minutes ago. I filled the block with hot tap water. I used a few heat guns in multiple cylinders in the block, after 10 minutes this got the block warm to the touch but even the sleeves were evenly heated, never hot, just warm. I used some tiny copper tubing, and put a torch to it with a 5 gallon bucket of hose water on the other end, this sucked the water up the tube and put it into the block in a slow controlled manner as the tube is only 1/8". I continued this water which was steaming hot letting it mix with the hot tap water. It took about 30 minutes to finally become a hot engine. When this happened, I put my air nozzle to it and held my finger with gloves on and a piece of scrap rubber over the other hole and boom, bubbles formed around one side of the sleeve in cylinder #5 only.
So, if you're going to do a leak test in the block HEAT THE BLOCK or it will possibly pass the test with a false positive.
So sad my engine is F#$%#KED. I guess now I have to decide, used engine, Turner short block, LS1 swap if ACE get's it done sometime this late summer as they expect to.
What is the going rate for a used but working '03 '04 motor? I will likely pull the block out and heat it and press the sleeves out, I'm curious to know what kind of failure occurred.
Many thanks to all who contributed, hopefully others who come across this will be able to better pinpoint their issues.

To the rest of you saying he will destroy it without and ultragauge - bugger off.
