Mikes pic is a good representation of how to do it. The lower hole around the outer diameter of the filter boss needs tapped to NPT and an appropriate sized NPT to AN fitting installed, that is your oil "out" of the block. Then through the filter ( the outer passage) and the oil goes "out" of the filter through the center passage and into the center passage of the block.
What size NPT do you tap your block to mike? I know the lines should at least be -10
