For what it's worth, I have two sets of headers to try out on my hooptie build up. The two sets are;
GN1Performance (the shiny set in the pics).
Burhead (the brownish pair).
The Burhead set I bought off a memeber here used and quality wise they are very beefy, 14 gauge 304 stainless I believe. They did need some tweaking due to interference with my mini-starter and the drivers side flange was not flat. A torch and some elbow grease and both problems were fixed. You can see in the two pics of where the drivers side header was previously "massaged" to clear the starter and how it looks now. My only issue with them now is that the crossover pipe will need to be sectioned and lengthened for everything to line up perfectly.
I bring these up because of their similarity to the high dollar & high quality T/A headers.
The second set is the polished GN1 Performance set. Everything with these was spot on with one exception, if you look closely the drivers side header just touches on the motor mount bracket. Out of the car it's an easy fix for me but might be a bit of a paint to trim in the car, or maybe your car won't even need the work. Otherwise things fit like they should. They were also ported out of the box.
The major difference between the two sets is that these were most likely made off shore. They are a thinner stainless like 16 gauge probably. The clamps and hardware is a bit cheap in my opinion but at least they fit like they're supposed to.
Hopefully in the next few days I can get the engine back in the chassis and see how the exhaust fits with a turbo and downpipe. Then the parts will be hi-temp coated.
Here's the pics...
