The truth is, no one knows how the head will work exactly until it is proven in the field.

In about 20 years we will know for sure.
My findings are this, the thinner deck contributes to gasket failures and possible deck distortion of the block.
As for running hot, I have a billet alum head where the quench area is a full 1" thick. There is water above this area and exits to radiator in two places, between 1&2 and 3&4. It does not run hot, has not cracked and the gasket stays sealed. I am using ARP studs and torking to 55 ft/# only.
IMHO, Tod is on the right track by adding deck material to the block and also to the heads.
Also, IMHO, the cooling system configuration is at best marginal. By this, I mean the water pump being used to pull the water from the motor is incorrect. When the water is hot and the pressure is lowered (to pull water) cavitation is more susceptible. By simply using the pump to push water through the motor you will increase the efficiency of the cooling system.
Again, just my opinion. John
