Yes stock intake and plate. Hope your next try works.
If not it will suck, but you can try pulling the intake off and getting a big sheet of 120 or so grit sand paper and sand it on a table.
There's an idea! The gasket surface (intake side) is a polished surface. I'm sure that is a factor.
If I have to remove the intake, I might as well just Tig weld (or braze) the plate on permanently.
