I have to agree with the rest Kwanza, I know my s*** also (you also must consider I work on computers not cars for a living so my memory isn't the best) but wouldn't it have been just as easy to say the head bolts have different patterns and the combustion chamber is way to small on the 2ZZ which could lead to detonation and compression issues. Also you could have explained even though the 2AZ head is an FE head it actually handles boost very well and wouldn't be worth swapping out. I understand where you're coming from but this is the first time this question has been asked so just give a real answer, now if another person comes by next week and ask the same question then give a smart ass response and say search.
