Hmmm. I’m thinking there are other factors at play here then. Hinge mounts at the hood have any room for adjustment? Torsion bars have a bend in them (prior to install)?

Unless the torsion bars are binding somehow/someway, I don't think it could possibly be the issue. They don't do anything to provide alignment. All they do is provide upward force on the hinge. No location control. Just force.

Are you sure you have the correct hinges for the car? Did they change anything over the years?

How about pulling one of the three hinge mounting bolts out and verifying that the hole is slid all the way to the edge of the slot?

Something that just came to mind: before I tore the car down, and without the torsion rods, the front of the hood was flush with the fenders, but, I could lift it up and move it vertically. Without any other cars to compare to, I figured it was normal...but is it?

My hinges have a fair amount of slop in them. Again, figured this was just normal, and the torsion rods would pick it up. If they shouldn't, I'm thinking maybe the pins have worn grooves into all the bars, and that slack is causing my problems?

I'm not a body guy, but I don't think that's normal. A little play would be required, but not a lot.

How much lifting are you talking about? Eighth of an inch, or three quarters?

My hinges were smooth and precise. No play at all. I can’t see them wearing grooves into the rods... but even then that would be minimal play.

It's been well over a year now, so going by memory, but I think a lot. Probably the same 3/4" that it sticks up now. Definitely not an 1/8 or so.

Bars meaning the hinge bars, not the springs.

Mine are anything but precise, so this is starting to look like the issue.

Yeah, that ain't normal.

I know it's a pain in the arse, but how about taking the torsion rods back out and finding out where that 3/4 inch slop is occurring. I've done the torsion bars twice and they're not that bad. Once you figure out how things are supposed to go together, I remember it being a ten minute procedure.

Yeesh. If there is that much play in the hinge, replace them just to be safe.

I also removed my torsion bars and hinges as a single unit. Less stressful if there is enough play at your fender side. Then removed the bars while the unit was out on the floor.

Not my greatest cinematic achievement, but here's an attempt at a video. I can push the hood down flush, but the rods will twist it back up.

 

I can't offer much help but I've had that exact same problem, one side of the hood popped up 1/2" no matter what I did, never figured out but it is certainly worth checking the hinges for slop.
