I purchased a set of Hooker headers from Amazon for about $275 and they work great. As long as you don't have air injection into the exhaust manifold (I believe on yours it is in the heads themselves - like mine) then they are Ca. legal.
You absolutely need to get something like Thermo-Tec heat shield (the thick fiber matting with aluminum backing) and wrap the headers BEFORE you install them. You MUST add heat shielding as the headers radiate WAY more heat than the stock manifold. If you have any seized bolts, then grind off the heads. I had to learn that lesson the hard way. I also had to chop up my stock manifold to grind off a couple that were seized, but that's ok. I wasn't re-using the manifolds and I had a long neck die grinder with 3.5" cutting wheels to do the work. Do not shear those bolts and try to drill out later. On some of them it is impossible to reach.
