I'm going to assume that if it won't come up in pictures then it's close enough and youre overthinking it. 1* one way or another probably won't affect anything, you don't plan on cruising at 200mph. These cars were never precise to begin with. The good thing is that each bushing is bolted individually to the frame so that the cam adjusters can do their job.
Now if it WERE so bent that it was obvious in pictures then you might be out of luck.
If you put it all together and find out it's impossible to get it aligned well then you know the first thing to look at.
There isn't much else we can tell you past that without making whatever assumptions we want with no pictures. This is all hypothetical.
Good luck on your project.
