Z1 shorty Headers not fitting

[alexblair370]

So I've posted on here before about my recent group of mods and my troubles but today's I'm not sure anyone will have any tips. I purchased z1 shorty headers for the 370z I got them on the passenger side fully tightened and after much pushing and turning I almost have them on the driver side but I just can't get it. I saw something about someone removing some of the studs and you can get it but I would really like to avoid messing with studs. I have the headers past the steering rod and about ready to line up with the head studs but I just need like half an inch of space and I don't know how to gain it. I have been struggling with it for hours I was just hoping for some secret strategy to get the holes lined up or something. Thanks
