anyone tried summit headers?

I was looking on summit for a pair of headers for my caddy (I know its not a wagon, but the engine bay dimensions are nearly identical), and I saw that the summit long tube headers for a caprice were over $100 cheaper than similar flowtech afterburners (which is what I was going to get).

btw, the car will have a chevy 350 under the hood.

has anyone here put summit headers on their B body?
Do they fit ok? and moreover, (since I'm getting ceramic coated) will they rust out really quickly?
I am installing a dual exhaust crossover on the car and plan on running dual exhaust all the way back (money permitting)
here are the summit headers I was looking at.

Those are the correct ones, in SOME of the B bodies, the "K" brace on the passenger side needs to be notched in order for them to fit. Not sure about the D body.
