yes, that swap is doen all the time but doesn't cure the problem since there have been numerous 3L head swaps dieing as well...
Sad 1st day for an LJ78 prado

There seems to be some minor confusion here...
The 3L (2.8L) head is not the same as the 3.0L KZ engine. The 3L head is the common transplant for an ailing 2LTE...
The best solution is to not purchase a 2LTE powered vehicle in the first place. We have three here at the moment, one (now being parted out) was on its second head... the 3L head might be better, but it's not a guarantee that things will be perfect in the future.

Surprised to hear about 3L (2.8l) heads cracking, but are they OEM heads or aftermarket (ie:Chinese)?
The cooling system on the 2LTE is very prone to air locks. Anyone draining and refilling theirs should read this: Hilux Surfing - Workshop - Coolant Flush

Swaping the head is not THE solution. If the underlying issue in the cooling system that caused the overheating is not fixed the heads will keep on cracking. A possible 'underlying issue' is your driving style. 
Well said Psilosin. Just because it says turbo on the door dosn't mean it's a race car.

I certainly would not call myself an expert on the 2LTE as found in the Prado and Surf. BUT I have worked on a fair number of them now and can say, without a doubt, that there are multiple causes to the early demise of the 2LTE engine.
The radiator capacity is more than adequate when working with reasonable efficiency. However, many, if not most, JDMs arriving from Japan have horribly under-serviced cooling systems. Almost every cooling system I have seen has contained an inadequate amount of coolant for corrosion protection and is severely plugged up as a result (corrosion and water mineral products precipitating out of soluton).
I believe that many 2LTEs suffer from over-fueling issues, some of which is related to driver error, but much of it is a lack of service and/or improperly performing injection pumps. Over-fueling leads to excess heat that tends to localize in the head and exhaust system.
The heads I use, and have used in the past are all genuine Toyota 3L heads.
Here's an example of a 2LTE head and block that had a the typical coolant to cylinder leaking problem. Others we see have pressurization of the cooling system, which is typically a one way movement (no coolant enters the engine).
