I also use the ARP 1 inch stainless 6 point bolts, they won't rust and you can get a open end wrench on them if you need to. I use Felpro 1470 gaskets as they fit my headers the best. Regardless of which gaskets you choose make sure your header flanges are flat and true as welding tends to warp them, especially in the area of the center two pipes. The flatter the flanges are the better chance you'll have of them sealing well.

There is no need to apologize for asking questions, pay no attention to that other exclusionary thread.

Also keep in mind the tightening between heat cycles. That's the key. You may have to tweak them 4 or 5 times.

I have the Percy's soft aluminum gaskets and they work great. I used the bolts that came with mid Pacesetter mids. I put the headers on, retightened them after one heat cycle and two years later I have not touched them again.
