Small block 90* oil filter adapter

I scored one of these units at Carlisle this weekend. On the center bolt there was 2 different types of gaskets on it. One was a small washer type (with a thin rubber coating on it), the other was just round cork. I take it that the cork washer goes in between the adapter and the block (on the bolt itself) and the small rubberized washer goes between the bolt head and the adapter?
Next question about this thing is that there is no gasket/ o-ring to seal the adapter to the block at the outer mating surface. Can I just use RTV to seal it??

Thanks
