If you are talking 600+ HP, perhaps you should build your own? I built my own, it allowed me to configure the headers exactly as I wanted for my desired powerband. It also lets you make actual equal length headers(which 90% of headers on the market are not) with true merge collectors(again 90% of the headers do not have) with v-band flanges(instead of the cheap 3 bolt flanges). In the end building my headers took about 3 days of labor, but it was well worth the effort spent, I got my pieces here:

What engine are you running and how many horse power? I have to have mine custom made. Are you running cut outs?

In my 65 with 408w 640hp I custom fabricated 4-2-1 nascar style headers 1-7/8 primary merged to twin 2-1/4 secondary merged to a 3'' collector. It took a lot of fabrication, had to notch my towers etc. I did not want a sharp bend in the primaries coming off the head, cuz that is required with stock shock towers.
I think your only solution is to have a set custom fabricated.
For what its worth, I have about $1200 in materials alone just to build my headers, flanges, bends, choke collectors, etc all 304 stainless, plus a month of fabrication. So paying $2-3k for a set of nice custom headers is not that bad of a deal as long as the quality is there
Thank you so much for your help. I have come on this site to find help. I came here for help. And mostly have been insulted. I am in California where did you have your header built? I do have my shock tower notched out. I have RRS front coil overs. And total control power rack. I was hoping to find someone with the same set up. That was successful with this set up and maybe had a jig or measurements for assembly .
