Opinions On Head Gaskets

They sell a .020 head gasket spacer for my Mazda MA motor, used to keep the oil jet to head distance spec when you mill a head. Its just a .020 sheet of punched metal. You can O-ring a block for copper gaskets for cheap as they will loan you the tool and a roll of stainless wire is 13 bucks. Nothing that thin though unless you want to (un)roll your own annealed coppers as they require sealant around the water ports anyway.
