273 valve covers

I'm trying to clean up a set of these and was wondering how to remove the finned pieces without damaging them. Also they are supposed to be a satin sheen right? Not polished? Thanks.:thumrigh:

Take one of those plastic extendable blade utility knives and cut the glue underneath.

If they are the factory Commando/Charger ones, the covers should be wrinkle black. You can either try painting them, or have them powder-coated by our very own "Mistress Of Metal" CudaChick1968.

The fins tops should be shiny, along with the plug wire uprights. The rest is a satin-type gloss.
