Never had to touch the rack on mine with the crappy headers it had when I got it. I did have to unbolt the A/C compressor (not disconnect it, just move it a bit) and some of the manifold bolts are a pain to get to and easier from the top/others from the bottom etc. They were also touching the alternator which I believe had it's cover removed for clearance, but that's one of the reasons I ditched them and why the previous owner was going through alternators...
Sounds like they just don't want to do it.
