Header bolts and gasket?
I just picked up a used pair of headers for my 2000 ss. I wanted to get some nice new bolts but I wanted to make sure I order the right size and if there is a brand I should get. Also on the gaskets should I just get a new stock pair or should I get another brand?

For the exhaust gaskets, get whatever O'Reilly or Autozone has for your car in Fel-Pro brand. They should have a metallic facing on both sides and probably better quality than stock anyway.
For the bolts, search would do you well but here is a shortcut for you:

After going through the hassle of breaking off the $@&#! driver side REARMOST bolt and pulling that head just to get the remainder out, I decided to go with studs. Still they could break from exhaust heat cycling/flex/stress/etc. but hopefully at least wont break off just from me removing them next time. Apparently ARP sells such a thing but I bought some no-name kit from a guy on eBay. Stuff looks pretty good. I got stainless and paid about $30. Hopefully they hold up over time.
You can never go wrong with ARP though..you just pay for it.
Good luck.

The instructions that came with my headers insisted on this(no gasket) but I didn't feel comfortable until I got the studs. Now I may go back with silicone. Without studs, I saw a big mess in my future while getting it all lined up and the bolts in.
Just a small ring around each port on the head or what?
Thanks.

Yeah, just a small ring around each port, AND a small ring around each bolt hole. That way you're torquing against a relatively flat surface. You also want to get some of the silicone on the bolt threads - that helps prevent loosening.
Get two bolts the same size as the header/exhaust bolt, maybe a little bit longer. Cut the head off, and then cut a screwdriver slot in the end. Screw them into the head like a stud, just 1-2 turns. You can hang the header on those studs while you get the bolts started. Then remove the alignment stud and replace with a bolt when you're ready.

Never thought about the ultra copper stuff for a header gasket. Considering that the OE MLS gaskets are like $10 for the pair, I'm not sure I see the benefit, though. I only say this within the context that if you remove the header, you'll be cleaning up the residue. With the gasket, it's as easy as putting new ones in (or reusing if they're not old; the OE gaskets are very good).
