opinions on hooker headers

So what sort of options are there for PS headers? The other problem I think I may run into is that the wonderful people that owned the car before me decided to replace the /6 and make their own mounts for the 318... On the plus side they look like spool mounts, but they sit on a piece of angle iron on one side and square tube on the other welded to the K member. I hate to drop big bucks on TTI's and find out that they won't fit because my engine isn't EXACTLY where it needs to be (that's at least the impression I got from reading the TTI footnotes). Are they just saying all that to cover their backs if stuff doesn't fit? I was going to try to measure up everything and see where I stand, it may not be that far off, but I don't know if I'll have issues running into the motor mounts.
