What head gasket for boost? MLS leaking oil

Hey guys
I am running 10 psi on my wifes 360 magnum through a supercharger. I fitted some MLS gaskets but they leaked oil as I only machined the heads. So i pulled the engine and machined the block and the heads and fitted a new set of gaskets with a special spray to seal it. They still leaked oil. So i fitted a set of thin graphite gaskets and tonight i just blew them out.

What are my head gasket options. I may just blow other gaskets out. Even if i use thicker ones but if i use the mls gaskets they will leak oil. Very frustrating. The mls gaskets i used were for a LA 360. Are they different to the magnum mls gaskets?
