Best Way to Seal Right Angle Oil Filter Adapter

I did the right angle dry about 7 years ago and it has never leaked.
I am upgrading to dual master and KH discs and I am using an aluminum MC form Dr. Diff. I am really happy with the one I got from hima and put on my '69 Cuda so that is what I am sticking with.
On another note is is power brakes? If so I wonder what MC to use in that instance....
