First of all, those pictures are very evident that the intake manifold is bare aluminum. Second, SOME NAPAS DO ENGINE DIPPING. What he's talking about is they dipped it in a solution that breaks down all the grime. It is a strong solvent, and most solvents of its kind have stripping agents, and would have removed the powdercoat without a doubt.
However, it may be a stripped SE intake. I can't tell that for sure. Just giving some input. I'm an engine builder and a powdercoater. Take that for what it's worth.
