Thanks for your input. I have that earlier Service Letter I just thought it would have been superseded by the one I referenced. But you must be correct that it just refers to solid lifter engines. I must be reading the diagram incorrectly in the Vol 22, No 14 letter because that hook-up just doesn't make any sense, it's just a loop between the sender and the filter.

If the sketch in your post is correct then my setup is essentially backwards, my bottom port of the filter goes to the block just above the oil pan and the side port goes to the block oil gallery via the pigtail. The other difference is that they swap the definitions of inlet and output ports on the filter. So I'm still confused as Hell.
