Oil filter plate leaks?

I'm chasing a bad leak on the filter adapter plate on my 360. Not using the 90 degree adapter just the plate.

How have you folks solved this stupid plate to block leak? I tried cork, rubber and the factory gasket all of them leak. I dont wanna use right stuff as it will be a major ***** to clean off if I ever need to remove it but i will if that's what it takes?

Also with just the plate do i use the small gasket around the part the filter threads on to under the plate?

Thanks for the time and advice.
