So although you can, it sounds like it would defeat the purpose.......and I'm sure there has already been an attempt to find a stock piston with similar bore and pin characteristics to 2uz with 1uz dome characteristics..... :(

Thanks. I have been following Lextreme with much interest. I am trying to accomplish 4.7L Hybrid without changing out pistons. I understand that 2uz design is different from 1uz design so there will be clearance issues with 1uz head. The optimal design is custom pistons however I also...

From various searches I have read that you can use a thicker headgasket for NA application when mating 2uz block to 1uz head in place of machining pistons or getting custom Ross pistons although the results are not as good as a custom rotating assembly. Due to cost entailed when opening up a...
