Okayyy... Hopefully I can give you some helpful information, without insulting you.
First, I have nothing like your car. So what I have to say may easily be debunked. I have an e-body with a small block engine, magnum heads and a mini starter. I went with Doug's Headers and haven't regretted it one bit. The finish was amazing, they have thick flanges (that was very important to me), and the fit was perfect. I did not have to thread my steering linkage through the pipes or remove my starter, and I have no problems clearing the spark plugs. Having a gooseneck ratchet adapter could've helped; the bolts were a bit hard to torque in a few places. On summit racing I see Doug's makes headers for your application. I would highly recommend them since they have an easy to install design, look great, and seem to have very good flow characteristics. The only issue I had was that the reducers that came with them were too small, I wanted 2.5" and they were more like 2". Check out part DOU-D451 or DOU-D451-R on summitracing.com.
