Hey guys.
If you read this thread

Then you know what happened.... Anyway I got a Mitsu MLS 4 layer head gasket from MAP. My question is proper ways to seal it. I know all about decking both head and block, but some guys say to clean and lap the block. I also head some guys using copper spray, or using oil to seal, how does that work? What should I do.
