i see that one of the smaller ones is bigger then the other..which ones goes to the wastegate, and which one goes to the turbo...

I don't think it matters which stem goes where, as long as the long one goes into the TIP. The two short stems are always open to each other (turbo to wastegate always flows). When the N75 is opened by the ECU, the long stem opens to the TIP, causing the wastegate pressure to get purged into the intake, increasing boost.

I always thought that the J valve is installed in reversed. The H valve is installed like the OEM. The J valve is a little Mild compared to the H. It may change depending on setup.
