billet or polished fuel rail for ls1?

[James OLC]

I was on a similar search for my LS7 (except I was looking for a black rail) and ultimately purchased an Aeromotive rail kit (which came anodized red) and had the original finished stripped and the parts recoated in Black by Pacific Coast Anodizing in Fresno, Ca. They came out really well and the whole process - stripping and recoating - took only a day.

You could look into an option like that. If you want a natural or polished finished you could have the rails stripped and then polish them yourself.
