I went through this last year. The seals are all Reinz. I also used the Besian procedure. If you look at the front timing chain cover with the valve covers off, is it even with the head. With the new seal sometimes it wont squash down and it will stick up a millimeter which throws the cam sensor off by that mm and throw the code. Both banks need to be within 12 degrees of the crank shaft rotation. The front covers need to be loose when installing the valve covers. I tightened the valve cover then the front cover and still had that mm. Once I accounted for that mm on the wheel it went into time. It only has to be adjusted a very small bit. If the hole matches up with the factory inspection hole just move it a small bit. I moved the wheel about 4-5 mm the first time when it should have been the one mm or less. That was my problem.
