BBC finned valve covers! anybody else running these?

[sir_talk_alot]

just got hooked up on a set of old cal custom finned bbc aluminum valve covers.i helped a friend track down a f+rd y motor for his model a 'rod he's building and he gave me the covers as a thank you. ive always liked the classic look of them. itll be awhile till they are installed, ive got to build the 454, but anyone else running them? im not sure if i want to polish them up or leave them the satin look, or even paint them. id like to see what other people have. thanks, mike
