What head gasket for boost? MLS leaking oil

Hey guys thanks for the replies
I have stripped the heads off and I have blown both head gaskets out Into the valley. I think it was must have been timing that's caused it and poor head gaskets. The heads were machine but the deck wasn't. I don't really want to pull the engine completely down and get the decks machined. Some I'm looking for a head gasket that will handle just over 10 pounds of boost. The mls gaskets will leak oil if i use them
