Uneven headers?

[Scott76]

So this is a weird one. After having gone through the 9 million things the previous owner did that were beyond bad, I have finally gotten rid of the junkyard header setup and mounted some Summit 1-7/8" primary headers. Fit up was beyond easy, clears everything. Weird thing is, the passenger side header is about 1/2" lower than the driver's side at the collectors and pointed a little bit towards the ground, the drivers is level.

Has anyone experinced this?

I'm welding up a custom exhaust and a custom trans crossmember so it's not something I can't overcome, but it seems like something is way wrong.
