Valve cover clearance

My 440 was touching with finned M/T valve covers. Hd to shave the fins down a touch

saw a post somewhere about a shorter blower motor that will interchange on the a bodies, but haven`t stumbled back on to it yet. facing the same thing in the future ,I`m sure.
if anyone has this info, please share it w/ us.
seems like it was off of an older dodge p/u.
