Twin turbo manifolds

[2keaton11]

Who makes a good set of headers/ manifolds for a TT setup on a ls3 in a 1st gen camaro. I found a complete TT kit for a SBC for 800 bucks with brand new turbonetics 56mm turbos, gauges, manifolding, everything new but I don't want to buy yet if headers are going to be 2gs and car isn't complete yet. I would like ones that mount them at the front of the engine. I have a street and performance front accessory drive kit.
