fiyota said:I would just like to point out, that even tho the car was running for only a minute overheated, as soon as you shut it off the coolant stops flowing, and starts to get hotter, and the motor will sit there cooking for as long as it takes for everything to cool down... just thought i'd mention it.
And this would help anneal the head ......supraman2251 said:at the same time, he was coasting, which cooled down the water in the radiator, and then started it back up, recirculating the cool fluid into the engine, and bringing the hot coolant out.

jdub said:What happens is you delay the coolant getting to ops temp (176-210)...this extends the time the ECU stays in warm-up enrichment. You want to run a thermostat...180 deg is fine for hot climates; for most the stock 190 is appropriate.

Aluminium that's been heat treated to make it harder (our heads) can be softened (annealed) once heated past a certain temp and cooled.
The Exhaust side of the head can easily reach this temp if the coolant is low.
