I have recently tried tracking down OEM B20A head gaskets with no luck. I tried my past vendor in japan along with another one in japan and new zealand with no luck. Its either not available or being held back. They just said "maker controls part" and that was the best responce i could get.
So with that said i would like to compile any available resources you guys have. I did pick up an aftermarket set but im learly of using it with high levels of boost.
Anyone with alternatives please drop some information here. I have contributed a fair amount to the B20A information pool now im hoping others can help me out.
