i used Pacesetters,cheap too,like 300 bucks on this board ceramic and everything.however, the pass. side had 1 tube that had to be re fabbed,there are companies that sell direct fit LS1 G Body swap headers,such as BRP but the price is way out of control.

Do you have the part number for the pacesetters that will fit the G-body?
because if that is so these will also fit my A-body, and I can just not stomach the prices for A-body specific headers.
Thanks

Yes, they work fine. That is what I'm using.

Just a few notes, though:

1. The driver's side manifold has a one-piece flange/downpipe/catalytic converter. The flange is an odd-ball triagular shape. Since it is a one piece design (with the cat), most people do not include the flange to bolt to the manifold. I made one out of 3/8" steel plate using the flange gasket on the manifold as a template. Here's a shot of the funky flange on the driver's side I was talking about:


2. You will need to get a 02 sensor plug and install in in the driver's manifold because there is not room to install the sensor at that location. Just have the exhaust shop install one in your downpipe. They will have plugs for the 02 bung in the manifold.

3. You will need to fabricate EGR block-off plates for both the driver and passenger manifold.
