Totally Stainless Header Bolts I have been going all out on my car and not trying to do anything to cut corners. I purchased Kooks headers but to put them back in with the stock bolts would just be a disgrace.
I purchased the "LS1/LS6 Header Kit" from Totally Stainless. The bolts are ARP bolts made from 16-6H stainless with "ARP" stamped in the head and polished to a shine. One thing i would like to say is that i spoke with the engineer there about the material properties (as an engineer myself, its nice to hear real info). These bolts have a tensile strength equivalent to grade 8 steel bolts.
I deal with different engineering companies all day and for a bolt supplier they were top notch!
I wish i had a camera to take a pic, If it were up to me, all my designs would have bolts like this... but alas, the bean counters have the final say.

You can order the catalog for the part numbers www.totallystainless.com
But the header bolts i got are Part #5-1540 (6-point), or you can get 5-1541 (12-point) but if it gets tight, you cant use an open end wrench on a 12 point. They both come in a pack of 16.

I, too, have these bolts...I have bought alot of stuff from Totally Stainless...they are great folks to deal with. Here is a link to a picture of a bolt I posted in an old thread:

I bought their entire LS1 engine kit...the bolts in the kit are standard strength stainless allen head bolts...the only high strength bolts I received are the header bolts. They do have a nice selection of "a la carte" ARP stainless high strength bolts, though...I bought nice 12pts for my water pump and belt tensioner...
