Need Opinions on 13b Engine cleaning up
 

Hey everybody, I've recently taken apart a blown 13b engine and have taken the Rotor and Rotor Housing to sandblast and then polish up and use as decoration in my house, because why not, right? Lol

Anyways, my question is (due to me being indecisive) should I just remove the outer parts of the housing? It's never going back into use obviously. Not all things....more so the 2 screws on be outer left of housing (in photo) and also the one sticking out just above it.

Has anybody else cleaned these up and used them as decoration of sorts who would have any suggestions? Thanks all!
