SB turbo headers?

I figured they were thin. I used 16gauge, a lot of those are 18 gauge



Though the Turbo idea is a relatively new one for me, after spending damn near every weekend at the track this past summer i've become pretty convinced that Turbo's ain't no joke.
I haven't purchased any parts yet since I just started reading a book about Turbo's and want to understand what the hell i'm doing before I just start buying parts , I am SERIOUSLY considering the addition of a single or twins to a 408 in my (primarily street) 65' Cuda where space is at a premium and I've yet to see any pics of a Turbo installed in a 65' on a V8.

I've never been one to utilize cheaper components and prefer to wait if necessary until i've got the coin to get the "better" stuff, this is actually the first time i've seen small block manifolds offered and already like the idea 16 vs 18 gauge.

I'd be just drooling to see the Turbo setup in a 65' if anybody has pics of that.
