Oil filter adapter gasket

on the 90° small block adapter is a cork gasket in the center. In your case i'm not sure. But the rules are: the oil is running into the filter through the outside holes and exit through the center hole. if the middle is not sealed, the dirty oil can bypass the filter.
Take your time and measure.
Depends on the year of the block. Magnum blocks are a different off set. They can be identified by having 6 holes instead of 4.Early are 4 holes and take a inner and outer or they make a gasket that is connected like a wagon wheel. You can see on the pictures below they inner and outer are the same height. Be sure to have the holes milled to the larger diameter as seen below for a high volumn pump and use a Wix filter or NAPA gold. Many oil seeps are caused at the outer gasket by not doing this when twisting these motors up with thick oil. Just something we do.
And don't leave rags under the intake like the last guy that came here.

Wow. Had a customer kill a low deck deal I did just like that.
Too many cooks in the kitchen and they left some rags in the lifter valley. It took 5 runs to kill it. It went slower every run, but they didn't bother to stop and try and figure out what was going wrong. And BOOM. Out comes the bones.
That plate you have there will not work on an early LA motor 273 , 318, 340, 360. That is for a later magnum , race resto or R3
One outer gasket is what I used on my resto block with the same plate

Anybody know for sure what the factory did?, every engine I have pulled apart that seemed stock had only a circular gasket on the blockside of the plate and nothing else. Felpro used to have the "wagon wheel gaskets" and they always leaked on my stuff so I just used the circular gasket and nothing else,I don't think felpro even makes those type of gaskets any more as the last few gasket sets I have did not include them and I cannot find them anywhere for reference.
The wagon wheel gasket is for the offset oil filter adaptor. The other gasket is for ur flat plate. No Center gasket. Kim

The parts book shows only the outside gasket with the standard mounting,
The small washer is only on the 90^ adapter.

That makes sense in that you could rotate the adapter and keep the gasket centered, funny thing is that is the exact setup that always leaked and I just used a std. gasket to cure it. I also noticed the new adapters come with std. gaskets.
