Notes on Install:
When winding the studs in on 1FZ, you will notice that they can go too far down into the block, leaving not enough thread for the nut. With the head on, we recommend putting the nut on flush with the top of the stud and then wind it in to correct height before starting torque sequence. That way you get full thread engagement on the nut, plus there’s plenty of thread length in the block.
