Ooff... I hadn't made it to the gasket yet. I started looking more closely at the copy I made of the cut/install sheet. It would appear that this was originally designed for a BD engine. It's blurry, but I think it says BD 220,240,264. All of the BD filter housings I found pictures of show a growth on the back cylinder side of the housing. I'm wondering if this was an early production/prototype item. I see the BDs and the SDs appear to share the same oil pump. Suggesting that the oil gallys in the block are similar. It would seem the position of the ports in the filter mounting boss are the same. They are both capable of using the same "Deluxe" oil filter. I found a bd/bg engine manual. It describes in pretty good detail how the full flow filter housing works. One of the valves is a high engine pressure relief valve- the oil will dump to pan. The second valve is a filter bypass valve- if the filter pressure rises over 12-15psi. The valves are supposed to be marked in the housing. I didn't see the markings, but some basic probing should sort that out.
Because this is missing the "growth" on backside I think it's just the ticket for my engine.
