Ive a good half fill in my 410 with a crs ele pump and cross flow rad, as well as a 19 row oil cooler, full trans blanket and [Email]B@M[/Email] cooler with fan...one fan on I can keep it at 180, two fans 160 on a street car with no worries, I worry more about the rapid cool down cycles vs running hot...

On shutdown from 180, it can hit 120 water temp in a couple minutes , I shut it off there and let it cool natural.

On last freshenup I did notice the area hard blocked had the high temp paint blistered from the heat it holds but at the same time things have stayed good enough in still running the calico bearings from the org build over 3 years ago.

With arp 2000 bolts they will get changed next time as I run them through 2 stretch cycles when new and 4 times apart they are done next time around.
