318 exhaust manifolds on a 360

This should be the last of it unless I buy more manifolds and make more tests on the driver's side or unless anyone has a question. But from what I've heard I should just stop trying because everyone's already tried everything.
As every one already knows the main reason it's so hard to fit a newer magnum manifold into the late 60s a-bodies is because of the power steering and/or manual steering box and shaft. Since I've never tried it on a manual steering box I reserve the right to see for myself. But as you can see in the last pic below, the factory driver's manifold kicks way up as soon as the ports leave the head. Big block manifolds are designed the same. The manifolds kick up to avoid hitting the steering box/shaft.
The first four pics show a stock driver's manifold lined up with a magnum so you can see why the problem exists. Now I realize that many member's are already aware of these details but I'm writing this for anyone who hasn't yet bought any magnum manifolds and might have questions. The slender piece of wood represents the space that the steering box and shaft would occupy. This is just a general representation. Since the magnum manifold comes straight out and down as opposed to straight up you get interference. I don't know (personally) if a magnum will fit in between the small block head and the steering box/shaft but many have said that it won't. The only one I did try on the driver's side came out of a car that had the starter on the passenger's side and because it hit the Mopar starter I could never get it in far enough to really tell anything. Since I personally haven't tried every large hole manifold out there (although I have a long list of possible donors) I can not say for sure. But I do know if all the large hole manifolds come straight out and down and if they are all just as thick as the one I tried on the driver's side, the odds are against you. In my case I happened to come across a good bargain on a driver's side 340 manifold so I stopped looking for a solution for that side. I then focused on the passenger's side and eventually settled on the one I recommend in my post.
The purpose on my posts here were to let everyone know, in my opinion, which large hole manifold is the best for the passenger's side, how to easily identify it for purchase, how to modify it so that it flows better and to help answer some of the questions the OP had at the beginning of this thread.
I have one more experiment to try on the driver's side. If the results are positive I may have more information...if anyone is interested???
