I removed the starter to get to the bolts on the end of the factory exhaust manifold. I don't have a lift and had to do everything from the top side. I think I could have installed the headers without taking off the starter had I been able to have the car on a lift or if I could have found my flex socket to remove the bolts. Murphy is alive and well at my house. Things just disappear.
I put ARP studs in the head before I installed the headers and used the 12 point nuts that came with the studs. I had to chase the threads in the head to get the studs to mount the correct depth, but other than that, it was an 1 1/2 hour job to remove the old manifold, clean the threads, and install the headers, start the motor..
It don't get much easier than that. Now I have to hookup my mufflers and I will go to the muffler shop for that work.
Hope this helps.
