Firehawk853 has some of the best off the shelf headers for an ls1 fbody. now obviously an fbody is a poor mans car, but still. these are TWO (2) headers, for 8 cylinders. full 2" (1.75" is the standard), full 304 SS, tig welds, port matched P&P, thick SS flange, equal length, with a top of the line collecter, just really nice header(s). 2" is quite large as well, AND this is with the brand cost. $900-$1000
