You don't just rip the head off, pull the gasket off, slap the new gasket down and torque the bolts down.
My thoughts exactly when i did my head gasket on my d15 i found every flaw imaginable and didnt check for it being warped only because the block and head were so pitted in every area imaginable i decided to put it all back together and run till it died.
Also is there movement in the rad like the water pump is working properly? in this situation i would have my thermostat removed till i figured out the issue. you could have a bad thermostat as well even if its new.
