Torque spec for 727 deep pan filter/extension screws?

Hey Folks,
Anyone know the torque spec for the 3 filter screws on a 727 w deep pan extension. Not finding it in any of my manuals. Historically I've just snugged them up by hand, by trying to do it "by the book" this time to ensure a good seal with the valve body. Thanks as always!

I've never seen a torque spec for the filter either, but being they are small bolts and fine thread going into soft aluminum I'd just tighten them as usual. I snug them until the filter mounting rings start to compress, using a short wrench and go by feel.
