It's pretty, I can't argue that but... In some cases pretty isn't best.
I don't know if that timing cover is polished aluminum or if it has been chrome plated.
I haven't had personal experience with them either. From what I have read over the years, the chrome plated timing covers leak everything everywhere. Considering how the chromed water necks leak, why wouldn't a chrome timing cover do the same ?
If there isn't any plating on the mating surfaces, no worries. If there is chrome plating on the mating surfaces, good luck with it.
